Mark Zuckerberg's social network has lost much of its swagger over the past year. He once thought nothing of poaching Google's best and brightest; then Google started poaching back. After Facebook's flacks learned that Google had scheduled its holiday press party on December 8, the same day as Facebook's planned media fest, they rescheduled for December 10, rather than fight for reporters' affections. Embarrassing — especially considering that Facebook's top PR guy, Elliot Schrage, came from Google himself.

When visionaries clash, whose vision do we believe? On newsstands this week, Newsweek's Dan Lyons savages Tesla Motors, the electric-car maker. Tesla was once the brightest hope of Silicon Valley's clean-transportation industry; now on its fourth CEO in less than two years, it's better known for manufacturing boardroom drama than actual vehicles. Lyons writes that Tesla's Roadster is a "classic Silicon Valley product — it's late and over budget, has gone through loads of redesigns, still has bugs and, at $109,000, costs more than originally planned. Company founder Martin Eberhard (left, at bottom) says that lead investor Elon Musk (left, at top), who recently installed himself as the company's fourth CEO, made costly changes to the car's design and is "a terrible CEO." Musk's retort: "Martin is the worst individual I've ever had the displeasure of working with."Eberhard and Musk have long feuded, even before Musk ousted Eberhard as Tesla's CEO. But I'd note that for once, they're not outright contradicting each other here. It's far more common for Musk to have a version of events that conflicts with everyone else's accounting. His history of events at PayPal, the electronic-payments startup he cofounded, seems to be shared only by him. And Musk has been telling everyone who will listen that SpaceX, his rocket startup, has a "Nasa contract to build the Space Shuttle replacement after 2010." If you ask Nasa administrators, they'll say that's more than a stretch of the truth. (In fact, SpaceX is competing for a contract, but it has only hit some of the milestones; Nasa is currently planning to rent out space on Russian rockets to supply the International Space Station, and a future supply contract for SpaceX is a possibility, not a certainty.) So Musk has a tenuous relationship with reality. Is this a handicap in his business? Apple CEO Steve Jobs is famous for his "reality distortion field" — a charisma that leads others to believe the most exaggerated claims, because the vision behind them is so compelling. Of course, Jobs actually has brought his outlandish vision to life four times: With the Apple II, the Mac, the iPod, and the iPhone. Musk has realized the Roadster, and SpaceX has managed, after several crashes, to launch one lone rocket. He's also got SolarCity, a startup which installs solar panels on roofs. If in 2011, we live in a shiny future where we drive Tesla cars powered with clean electricity from SolarCity panels, and SpaceX's Falcon1 rockets are supplying orbital space stations, then we will be living in a reality of Musk's making — much as Jobs envisioned the iPod in the dark days of October 2001, and then, three years later, saw them everywhere on the New York subway. There's another possibility, however, which would also make Musk like Steve Jobs — the Jobs of two decades ago, who was forced out of Apple by the CEO he hired. Tesla could go under, SpaceX could fail to win the Nasa contract, and SolarCity could get beaten down by rival cleantech startups. And then Musk, driving his Roadster on the lonely roads of Silicon Valley, would find himself facing a reality not constructed in his mind. An unpleasant thought, that. Far easier just to succeed.

Stewart Alsop, the goofy San Francisco-based venture capitalist, has this in common with Nouriel Roubini, the louche New York University professor known as "Dr. Doom" for his timely predictions of the current market collapse: Both are Facebook stalkers, aggressive in their requesting of friendship from attractive young women. But Alsop has one key difference: He's utterly shameless about it. Roubini was spurred into late-night Hitlerian name-calling by Gawker's reporting on his Facebook habits. We've sometimes felt the urge to hire a bodyguard for CNET video personality Natali Del Conte when she and Alsop attended the same party.But confronted by Mashable about his relationship collection, Alsop freely fessed up: "In his mid-50s, Alsop reaches out to young attractive women and asks if he can be their friend. Many say yes. Alsop says he's an old guy and it makes him feel as if he's got something going on. There's no downside for Alsop. Some may think it's weird, but it doesn't change anything for him." In case you had any doubts on how free-thinking the Bay Area is on such matters, Robin Wolaner, Alsop's "No. 1 girlfriend" and the CEO of social network TeeBeeDee, supports her man's Facebook habit. Even though, in the same Mashable article, she recommends against accepting friend requests from people you don't really know. Like, say, her 50something venture-capitalist boyfriend.

Brad Fitzpatrick has a Googlephone, and you don't. And what's he doing with his amazing Android-powered toy? Using Google's mobile operating system, Fitzpatrick is coding an automatic garage-door opener, which senses the presence of his phone using Wi-Fi. He can do this because he's already hooked his garage door up to a Web server. Writes Six Apart executive Michael Sippey on this momentous occasion:

Let's keep this nerdfight short and sweet — no, make that bitter: New York-based blogger/consultant Allen Stern thinks New York-based videogame designer Charles Forman is jejune and uninteresting. Forman thinks Stern is fat. In a predictably deleted comment on Silicon Alley Insider, Forman rails at Stern for complaining about his frequent appearances at the New York Tech Meetup. Here's Forman's counterpoint:

Why did disgraced stock analyst Henry Blodget post a long email by Mahalo CEO Jason Calacanis to Silicon Alley Insider, and then take it down? There's the obvious reason: Calacanis hadn't given permission for it to be republished. But Silicon Alley Insider has reprinted Calacanis's emails before. We think it more has to do with the fight that broke out in the comments between Calacanis and Howard Lindzon, a Phoenix, Ariz. hedge-fund manager who owns a piece of Blodget's blog. Could it be that Calacanis's copyright gave Blodget a convenient excuse to unpublish the piece — an item that was generating ill will between one of his investors and a startup CEO whom Blodget thought it expedient to suck up to?If so, the peacemaking attempt failed. Lindzon has made no secret of his dislike for Calacanis, on his blog and on Twitter after Twitter after Twitter. In a post discussing the bailout, Lindzon gratuitously dissed Calacanis as someone who "started a bad business (Mahalo.ugh) at the top and now is scared and panicking to his e-mail list." Calacanis extended an olive branch:

The Justice Department met with Google and Yahoo's customers and competitors this week as it continues to build an antitrust case for its litigious hired gun Sandy Litvack. On top of that, Canada is now on Google's case too, having hired antitrust lawyer David Kent. Never heard of him, sure he's a hoser, eh. In response to all the haters, Google just made itself another enemy: Kara Swisher, the mean lesbian mommyblogger employed by Rupert Murdoch and partnered to Google executive Megan Smith. Fun times at home!Google's mistake: Creating a PowerPoint presentation and posting it to a site with the search-engine-optimized name "Facts about the Yahoo-Google advertising agreement." In the presentation, which we've embedded below, Google explained that the deal is not a merger and that Ford uses Toyota engines in some of its cars. It also misquoted Swisher, making her really mad. The presentation cites Swisher as saying:

Multimillionaire CNET founder Halsey Minor is in the news again, for another spat over his expansive art collection. Portfolio explains that Minor got into an "angry email exchange" with famous artist Damien Hirst. There are now "gaping, fist-size holes in the plaster walls" of Minor's San Francisco offices, where Hirst's work used to hang. This comes as Sotheby's is suing Minor over a disputed art auction. After the article ran online, Minor left a rambling comment quibbling with details. But he never disputed the story's central question: Has Minor spent so impulsively and unwisely on art, real estate, new startups, and a new wife (Shannon, pictured with Minor, above), that he's running short on cash? He doesn't answer that. Instead, he declares himself "the baddest psycho in bass fishing." The comment seems as delusional as this moment he recounts in the story:CBS chairman Sumner Redstone walked past him at the Bel-Air Hotel, shortly after CBS bought CNET for $1.8 billion. Minor hasn't been at CNET since 2000, and wasn't involved in the sale. So why would he expect Redstone to recognize him? Nostalgia? Pity? Portfolio reports on Minor's many difficult relationships; he told the magazine that Gateway founder Ted Waitt, formerly an investor in one of Waitt's startups, is no longer a friend. Add to the list of those difficult relationships: Minor with facts. (Photo by Rob Howard/Portfolio)

In the war of words being fought between the organizers of the DemoFall and TechCrunch50 startup conferences, AllThingsD reporter Kara Swisher unleashed quite a salvo yesterday: "Being lectured on journalism ethics by Michael Arrington is like getting parenting tips from Britney Spears." Zing! She proceeds to call out the TechCrunch50 organizers attacks on Demo for what they are — "Marketing 101." Walt Mossberg was a bit more diplomatic, offering more subtle jabs like, "It never occurred to me not to come here [Demo]." Here at Valleywag, we maintainthe highest standards of impartiality through our willingness to get kicked out of any and all such events.

Click to viewKnow that old saying "keep your friends close and your enemies closer"? Former Engadget editor Ryan Block has put it into practice by tapping former Gizmodo editor Brian Lam — now the site's editorial director — to help advise them on their new gadget startup gdgt. In doing so, Block has ended — or at least set aside — a long-term gadget-blog rivalry which frothed with animosity. (Gizmodo, like Valleywag, is published by Gawker Media.) At times, the competition got dirty — like the time Block created an anonymous blog slamming Lam for a post about the iPhone.Block has since confessed to the stunt. In a post on Lam's hire, Block says "Brian Lam and I are actually pals outside of work — have been for years." But back in 2006, a tipster told Valleywag, Block created a blog called Boycott Gizmodo! and a Digg account with the same name that he used to promote blog's one and only post to Digg's front page. "The time has come to Boycott Gizmodo," reads the post. "Not only did Brian Lam and Gizmodo purposefully deceive long standing readers such as myself about the iPhone, they did a terrible job of covering their tracks." (Lam's post promised readers news about an "iPhone" device on a Friday, before the launch of the actual device — and then, on a Monday, revealed that Cisco owned a trademark on the term, long attached to speculation about an Apple cell phone, and had released an iPhone-branded product. The companies long since settled the matter, giving Apple rights to the iPhone name) We asked Block if he was the author of the blog. In response, Block told us, "Brian and I have always been friends who knew where to draw the line." Block also just published a confessional blog post titled "Bygones and rivalries," in which he confessed to authoring the "Boycott Gizmodo!" blog. He also offered another anecdote from a rivalry we're all going to miss.

Our summary of social-network operator Ning's tiff with a widgetmaker sparked a vicious name-calling riot in the comments. Elvenjewel became today's featured commenter by providing a helpful summary of the fracas, which proved more interesting than the Ning dispute:

Marc Andreessen's Ning is a platform for thousands of social networks. Mick Balaban and Spencer Forman's WidgetLaboratory builds and sells add-ons for operators of those social sites. Or did, until August 22. That's when Ning general counsel Robert Ghoorah wrote Forman to say that WidgetLaboratory would be booted from the site for breaking its rules. The charge: something about how their widgets "unduly degraded" the rest of Ning. Now, Forman's made that email — as well as 14 others between Forman, Ghoorah, and Ning CEO Gina Bianchini — available online. Trust us, you don't want to read them all. Here's the soap opera minus the froth:

Click to viewWhy might this this summer's batch of incubator Y Combinator's startups bore you, as they did "one cranky attendee" who told Silicon Alley Insider so? Because you're not as talented at spotting early stage startups as Y Combinator cofounder Paul Graham, says Paul Graham in a comment on the SAI post:

Our featured commenter, Robin Wauters, has one question for you about the latest spat between Mahalo's Jason Calacanis and Rocketboom's Aaron Baron:

In this corner, Andrew Baron, cofounder of hot videoblog mess Rocketboom, challenging Mahalo founder and incumbent blowhard champeen Jason Calacanis. Baron lands the first blow, citing Mahalo's "flat" traffic. Calacanis counters with some trash talk and then a body blow to Baron's privileged upbringing. Baron complains to the ref that the "trust-fund baby" charges were below the belt. Meanwhile, Calacanis argues with the judges that Baron shouldn't get the point on the Mahalo traffic jab. After the jump, the action continues.

Shortly after we ran the item about the writer who accused Jason Calacanis of plagiarizing from his TechCrunch50 conference's main competitor, we got this email from Chris Shipley, who has run the Demo conference for years. Short version: The text from which writer Deb McAlister-Holland claims Calacanis copied exactly 1,893 words may have been in a newsletter sent out prior to 1996. McAlister-Holland claimed her piece "was on the Demo website for three years," but no one's turned up either a copy or McAlister-Holland yet. Long version: Demo's current guide to presenters, below.

Here's the short version of a long story: The TechCrunch50 conference is a relatively new event cohosted by blog entrepreneurs Michael Arrington and Jason Calacanis. It presents itself as an Web 2.0 counter to Chris Shipley's firmly established Demo event, which itself was created as an antidote to previous tech shows. Both TechCrunch and Demo unveil new products and companies live onstage. Demo charges companies to participate. TechCrunch does not, and claims Demo is a "payola" scheme. Got all that? Great, now you'll understand why it's a big deal that a lady you've probably never heard of claims that 1,893 words of Calacanis's guide to pitching your company "were directly lifted" from a guide she wrote for Demo ten years ago. Deb McAlister-Holland hasn't yet produced her original article nor responded to attempts to reach her, so I'm skeptical. Chris Shipley says the article predated her 12-year stewardship of Demo, and disavows the charges. Jason Calacanis, plagiarist? Come on, that would require him to give someone else the last word.

ConnectU cofounders Cameron and Tyler Winklevoss, even as they're trying to wrestle a chunk of Facebook from former Harvard school chum Mark Zuckerberg, are training for the double-shell rowing event at the Olympics. Maureen O'Connor, an editor at Julia Allison's entertainment startup, NonSociety, hoped the privileged pair would send the site updates from Beijing. So O'Connor emailed Guest of a Guest editor Rachelle Hruska — who apparently knows the fair-haired Harvard-grad twins — to ask for an introduction. One small problem.Hruska noted that O'Connor's other blog, Ivygate, had called the twins "spoiled bitches that tried to lay one on the invincible Mark Zuckerberg and failed." We don't see the problem with hiring "spoiled bitches" to work at NonSociety — they'll fit right in with Allison! Had Hruska really been cutting, she'd have asked how Julia Allison's latest BFF, Randi Zuckerberg — older sister of the man the Winklevosses accused of stealing ConnectU's code for Facebook — would feel about the hire.

Violet Blue, the sex blogger Boing Boing tried to purge from its memory, managed to turn the "unpublishing" into a black eye for the Boingers. But she's been less successful on another front: Local courts have denied Blue's request for an injunction barring two Wikipedia contributors, Nina "Ninavizz" Alter and David Ben "Archeaopteryx" Burch, from editing her entry. Blue first filed a police report, then a civil harassment order. The order and any temporary injuctions have been dismissed, though Blue is allowed to file again if new developments arise. (How kind! Boing Boing didn't even give her a second chance!) In the police report which kicked off the legal tangle (reprinted in full below) the officer suggested Blue file the order with the courts and "inform the web page master of Wikipedia of the incident, give them a case number, and request to have her information on Wikipedia locked so the public cannot alter it in any manner."Critics have lambasted Blue for everything — from seeking the court injunction to having the filing fee waved due to a "credible threat of violence." We can't help sympathizing with her, because we know how difficult it can be to get anyone at Wikipedia to step in and moderate a dispute. There's only one sure-fire way to get your listing cleaned up — sleep with founder Jimmy Wales.

Trash hauler Republic Services was set to be acquired by Allied Waste Industries in a stock transaction worth $6.2 billion. But then Waste Management Inc. stepped in, matching the $6.2 billion offer but in cash. Turns out that through Cascade Investment, former Microsoft CEO Bill Gates owns a stake in both Republic and WMI — pitting Gates in a bitter hostile takeover bid against Gates. [Earth2Tech]
