What's so bad about Mozilla's Toronto workspace? Besides the fluorescent lighting, the colorless white walls and the folding tables, the worst thing about Mozilla's Toronto workspace is how we're sure management would improve it. With corporate graffiti, company logos and too many colors. That was management's trick at Facebook and look where readers ranked it in our poll on tech's ten worst workspaces — as tech's second-worst workspace, just after Mozilla. Check out the full list, below.

After reviewing our post "The 10 worst workspaces in tech," commenter AdmNaismith described Facebook's office, pictured above, as "foggy, dank, dim, and utterly depressing." Commenter mothra1 hated Yahoo's New York offices more: "They suck! Lifeless and impersonal. Kinda like the douchebags who still actually work there." Meanwhile, Adobe apologist BlairHapjo told us we "clearly didn't get past Adobe's lobby," and the rest of the office features "Aeron chairs, real offices (with doors!), big picture windows." For us, the worst offices we found on Office Snapshots and elsewhere were the the ones that try too hard to seem Internet-hip, like Jajah and Google. Now it's time to settle the disputes. Below, vote for your least favorite and help us rank tech's 10 most dismal places to work:

We've toured the top 10 workspaces in tech. Click to viewNow, we've gone back to Office Snapshots to find the 10 worst. What makes them so bad? Some offend with exposed fluorescent lights, gray cubicles and a dystopian corporate sheen. But others, with their pseudo-hip graffiti, kindergarten toys and plastic decorations — all in a desperate attempt to seem "Internet-y" — come off even worse. We'll start with Yahoo's New York digs.

Jajah
The poor souls at Internet phone company, Jajah. No one should have to suffer through so much purple outside of Sunnyvale. Also, when does corporate graffiti get added to ThingsWhitePeopleLIke.com? (Photos by Jajah)

Mountain View-based Internet phone company Jajah will soon provide the technology, billing and customer care for phone features in Yahoo's instant-messaging service Yahoo Messenger, the AP reports. The deal is part of Yahoo management's cost-cutting plans to turn much of its feature development over to third parties. Yahoo Messenger has 97 million users, but Yahoo won't say how many actually use its Internet phone service — probably because the number isn't nearly as impressive.

Have you ever wanted to tap into the entrepreneurial spirit that generates multibillion-dollar valuations? Do you dream of becoming a Silicon Valley icon? Crave the street cred that lets you get away with wearing Adidas Adissage sandals to formal events, to nicely complement your suit? Well, sirs and madams, you can't. But wouldn't it be awesome if you could pretend to do all that while drinking sugar water laced with caffeine? Telephony company Jajah already has its own energy drink — as do celebrities as shameless as Steven Segal. Obviously there's a market that Web entrepreneurs aren't capitalizing on — and it's too bad for them we're beating them to it.

We'd hardly blame Meg Whitman if, after this week, she decided to hang up on the phone business altogether. On Monday eBay said they were taking a $1.4 billion charge related to their acquisition of VOIP startup Skype. On Tuesday, we noted that one of Whitman's major goals in buying Skype, bolstering its auction business in China, where rivals were using click-to-call features on their auctions to close sales, has turned into a complete failure. And then, yesterday, things somehow managed to get worse.
