AOL Instant Messenger—the chat network on which millions of cubicle workers flirt with each other and tip off gossip reporters about their bosses—is down.

In our post "Tech's 10 worst-rated CEOs, according to their employees" a Microsoft employee complains that the only way to get promoted is through "technical knowledge and political savvy." Not true, another Microsoft employee tells us. At least, not under Steve Ballmer's regime.

Google has introduced Gmail Labs, a digital playground for Googlers to develop new features for Gmail in their spare time. It's a well-staged PR event, a timely effort to remind the press — and through them, potential hires — that Google lets engineers spend 20 percent of their time on side projects. Gmail Labs, though, is a sign of how 20 percent time as early Googlers knew it is vanishing from the Googleplex.

Mark Zuckerberg must be glad he's at the D6 conference in Carlsbad, where he has nothing to fear besides running into my boss. We've heard one of the reasons Zuckerberg left town in the first place was that he didn't want to be around when the company eased out CTO Adam D'Angelo, a high school friend of Zuckerberg's. Another the sensitive CEO skipped town? He may not have wanted to see the disappointment when his employees learned that the company would revoke a cherished $600 housing subsidy for those living near Facebook's downtown Palo Alto headquarters. Since reporting the news yesterday, more tipsters tell us the subsidy slash is real. According to one, new employees will get no housing subsidy and as soon as current employees sign new leases with their landlords or decide to move, they lose theirs too. "Something is going on at Facebook and it isn't good," observed commenter sggrf afer yesterday's news.

Google may have its free food and massage parlors, but Facebook pays its employees a $600 per month housing subsidy as long as they live near the company's headquarters in Palo Alto. At least, for now it does. "Yeah, they're talking about getting rid of the subsidy," a disgruntled Facebook employee told a local gossip who passed word onto us. Our source blames new Facebook COO Sheryl Sandberg — the ex-Googler picture on the right, who when hired "came and kicked everybody in the ass and said this is going to be hard," according to Facebook HR chief Christopher Cox.

Jim Buckmaster, the suspiciously tall CEO of Craigslist, hates meetings. "I've always found them to be at best unproductive and boring, and at worst toxic and destructive," he tells FT Deutschland. "The people who want to show off do, the brown-nosers brown nose, everyone else wastes their time. I also think the larger the meeting, the worse it is." Buckmaster prefers to email or IM, even while in the same room as his electronic correspondents. When forced to attend a meeting, he finds ways to kill time: "Meetings are excellent for doodling. I can remember doing some really, really spectacular doodles." Doesn't this explain so much about how eBay's relationship with Craigslist soured?

Zappos, the Nevada-based online shoe and accessories retailer, has an interesting twist on new-hire bonuses. After applying and being chosen for a job, employees get a month of paid training. Then they're offered $1,000 to leave. It's a test of commitment, meant to see if money is what matters to workers. The amount offered has risen from an initial $100 and could grow even more. Only 1 in 10 take the offer, according to CEO Tony Hsieh, and the company now employs approximately 1,600 who passed the test. Our question is, would you take the money and run or stick around to sell shoes?

Google's Taipei office used to be on floor 37 of the Taipei 101, one of the world's tallest towers. After a big move, it's now on floor 73. Flickr user tempofeng attended the move-in party and uploaded shots so the rest of us could marvel at the pace with which Google's kindergarten-themed offices march across the globe. The full gallery is embedded below.

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:

When we first listed tech's 10 best workspaces, we downplayed the importance of design and amenities. The crowd disagrees. It favors beer. Digg's beer, to be exact. 1,505 voted in our poll, and 28 percent chose the social news site's workspace and its fridge full of beverages as the best workspace in tech. Were the poll's results skewed because it hit the Digg front page? Possibly. But maybe second and third place finishers Pixar and Google should have thought about such consequences when they decided what businesses to get in. The full list, selected from Office Snapshots, ranked by readers:

The smack-talk inspiring contest of beer pong — known as beiruit in some quarters — scheduled between Facebook and IAC subsidiary CollegeHumor is off. Why? Because Facebook's PR and legal departments said so, CollegeHumor cofounder Ricky Van Veen told our tipster:

After reviewing our post "Tech's top 10 workspaces" commenter Dweezil complained that our choices were full of "to much modernism bullshit." Commenter Web2PointOhShit tore at everybody:

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.

Mozilla

Most people who work on Mozilla's products don't get paid. Actual employees in Mozilla's Toronto office have it much worse. (Photos by menros)

Mahalo

Mahalo founder and CEO Jason Calacanis not only pays his "guides" between $30,000 and $35,000 a year, he also houses them in what appears to be a poorly lit, post-apocalyptic strip mall. (Photos by Conrad)

Google

We listed the Googleplex as on of the top 10 workspaces in tech because of its amenities. But with its kindergarten campus color scheme, lava lamps, scooters, and ball pool, Google's headquarters often seem designed to to hide its most prevalent feature: gray cubicles. Anything to keep the drones from remembering that they're just one out of the corporation's 16,800 employees, we suppose. (Photos by titaniumdreads, emerce, tantek, revdancatt and yoz)

Microsoft

Microsoft's world headquarters in Redmond, Washington go the other way. Welcome to the Borg cube. No talking. (Photos by taguri and ilikeyesterday)

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)

Facebook

Food wrappers everywhere and a little smelly — Facebook's offices remind me of my sophomore hall. Except instead of drunks vandalizing the place, Zuckerberg paid a kid to go at the walls with a spraycan. This was done to reinforce Facebook's vibrant, youthful culture by ensuring any visiting adults would rather gouge their eyeballs out before ever returning.
