In an IM chat with ex-girlfriend Rachel Marsden, Jimmy Wales scolded Valleywag for not following his sex life more closely: "I have shown up at many different Silicon Valley events with many different "dates" through the past year or so, although not always actually dates, so the assumption would be colleagues or whatever, and figured they would eventually pay attention to that." True, Jimbo, we've been remiss. And we're doing our best to make it up to you. Besides Marsden, we've heard two names frequently linked to Wales, who is separated from his wife. Either would be an impressive catch. If the rumors are true, then all we can say is — well-played, Jimbo, well-played.

A tipster reports overhearing Jimmy Wales at SFO the morning of Saturday, February 23, pleading with a girlfriend — presumably Rachel Marsden — to keep the relationship alive. His eyewitness report of the conversation:

Michael Arrington's ex-girlfriend, Sun Microsystems heiress Meghan Asha, has purchased the domain Whoisyourarrington.com. Toward what purpose, we do not know. We just hope it doesn't hurt his feelings.

What's the worst thing Jimmy Wales could talk about with a girlfriend? Get your mind out of the gutter, and down into the sewer. Before his Wikipedia-posted breakup with Rachel Marsden, Wales plotted with the Canadian journalist on exactly how he was going to get her Wikipedia entry cleaned up. To avoid his foes at Wikipedia Review, he told Marsden he'd work through proxies. In a statement, he claimed he was not acting "inappropriately." Here are the transcripts which will let you judge for yourself. (Marsden is the "me" in this chat; Wales's moniker is "jimbo.wales.")

Looks like Kevin Rose and Julia Allison had a nice time in Miami at the Future of Web Apps conference. The pair were photographed sharing an ice cream shake by Fusebox founder Bryan Thatcher — a photo that subsequently was hidden from public view by Thatcher, but not before we got ahold of it. Here's the full pic:

Michael Arrington, a fragile soul, imagines the rest of the Valley is as weak-willed as he is. Without mentioning Jimmy Wales by name, Arrington distraughtly lays out his fears that Valleywag will drive him to kill himself. How little you know, Michael. For Wales, Valleywag induces not the big death but the little one. In his sex chats with Rachel Marsden, Wales fantasized about taking the Canadian TV commentator to a public event like this spring's Time 100 party, and wondered why Valleywag hadn't previously outed him. The transcripts, below:

Wikipedia founder Jimmy Wales and Fox News personality Rachel Marsden have broken up — and Jimmy is learning a harsh lesson: hell has no fury like a woman scorned. Here's the goodbye email from Rachel to Jimmy and an IM conversation that strongly suggests Wales violated Wikipedia's rules to encourage favorable changes to Marsden's Wikipedia profile.

Breaking up stinks. Never more so than when your ex is Jimmy Wales, the unhygienic founder of Wikipedia, right-wing TV commentator Rachel Marsden has learned. Before Wales dumped her via Wikipedia, he left two reeking articles of clothing at her New York apartment. She's now selling them on eBay Canada. Today's contribution to the sum of all human knowledge: Jimmy Wales shops at Men's Wearhouse. Screenshots of the eBay listings:

A tipster emails from the Future of Web Apps conference in Miami with a Julia Allison and Kevin Rose sighting. Guess that Pownce invite worked on Julia. The conference was described by one attendee as "basically a war between PHP and Ruby on Rails." Well, it seems like some are having a good time. Check out the tipster's email and full-size pics below, enhanced slightly for clarity.

This is surely a first: Breaking up with a girlfriend via Wikipedia. Jimmy Wales, the creator of the world's best collection of Outkast lyrics, has announced in a statement on the website that he's no longer seeing Rachel Marsden, the saucy Canadian right-winger who started chatting him up after her Wikipedia profile came under attack. (See Valleywag's exclusive transcripts of their secret love IMs.) One hopes Marsden didn't learn about the split by reading Jimmy's love note online. As late as last night, she told a friend that she and Wales had patched things up.

In which Wikipedia's chief non-expert Jimmy Wales worries that Larry Page and Sergey Brin will be able to read their instant messages, talks dirty about broadband infrastructure, and says his "Google killer" startup Wikia needs to make him enough money so he can buy a jet where he and Canadian girlfriend Rachel Marsden can have even more sex. Friends claim that Wales, worried Marsden would leak the chats, threatened her with blackmail charges over the transcripts, and talked about jail time and deportation back to Canada for her. That got her so upset she sent copies to one or more friends. They've landed in our inbox. Good job, Jimbo. The best bits:

Why did Wikipedia founder Jimmy Wales suggest Wikipedia move from Florida to New York last fall? His for-profit startup, Wikia, is based on the Peninsula; siting Wikipedia's nonprofit foundation across the country made little sense. In light of his fling with cantankerous Canadian Rachel Marsden, the New York-based TV commentator, Wales's Big Apple urges now seem clearer. We now hear he's told Marsden he intends to move to New York in April, after his lease on a San Francisco apartment expires.

Men, if you want to win over a girl, don't post ads on Craigslist. Instead, help her clean up her Wikipedia page! It sure worked for Jimmy Wales. The twice-married, now-divorcing Internet stud met his current girlfriend Rachel Marsden through the site. Here's a brief recap of the Web courtship:

Jimmy Wales loves to talk about "transparency" and "a world in which every single person on the planet is given free access to the sum of all human knowledge." Unless it's about his scandal-prone girlfriend. Wales, who is divorcing his second wife Christine, has been secretly seeing conservative TV commentator Rachel Marsden since last fall, friends say. Wales apparently took notice of Marsden when Wikipedia users started an edit war over her page. Marsden, known as "Canada's Ann Coulter," has quite a history: She's been accused of stalking. She plead guilty to charges of criminal harassment in 2004. Most recently, she was escorted out of the Fox News building in New York after an alleged contretemps.

Michael Arrington sat for an interview with Portfolio and they hit on all the important topics: Silicon Valley's "pirate" entrepreneurs, venture capital's relationship with the stock market, and of course, Arrington's love life. The nonboring bits:

Julia Allison writes that she signed up for a Pownce account despite not knowing "what, exactly, Pownce is or does." (I'm with you there, Julia.) She says she signed up because "I was told to sign up, and ... I follow instructions when given by cute boys." Well Kevin, that's one way to get signups. Just be careful down there in Miami at the Future of Web Apps conference, 'kay? We hear there's a big pink target on your back.

*Paul Boutin, our local heterosexual, told me I had to say it like that to avoid sounding gay. Apparently "charismatic dorkiness" is the verbal equivalent of a punch on the shoulder. Did it work?

Michael Arrington and Meghan Asha aren't on-again, off-again anymore. Sources with intimate knowledge of the situation tell Valleywag that it's unambiguously over. We're confident a man with Arrington's prospects will have no problem moving on. Asha, it seems, already has.

Four eager tipsters inform us that TechCrunch editor Michael Arrington is once again single. We hope this doesn't mean it's completely over between Arrington and his on-again, off-again fling, Meghan Asha. But if it does, we just hope Arrington has learned his lesson. Next Valentine's, Michael, send flowers. Then, late February next year, maybe you won't still be looking for "a relationship" and "dating," as your profile indicates.

Meghan Asha — the SIlicon Valley heiress who keeps TechCrunch's Michael Arrington as her on-again, off-again boy toy — found a new dog to play with at yesterday's toy fair in New York. Improvements over Arrington: He can't talk, but he can wag his tail."Do you want a date?" Asha asks. "Do you want to come home with me? I would take really good care of you." Below, in another clip, Asha in a lurid threesome.
