Says commenter The Default Attorney about Facebook recruiter Meagan Marks, one of the Valley foxes we featured recently:

Six big U.K. advertisers just took Facebook off their friends list. First Direct Bank, Vodafone, Virgin Media, the U.K.'s Automobile Association, Halifax Bank, and Prudential all took offense when their ads appeared on the British National Party's Facebook group page. Many cited corporate policies prohibiting ads from appearing to support political parties. Virgin Media, more forthrightly, simply needed to "protect its brand." No wonder: The BNP has called for Muslims to be banned from Britain's skies — one of its less extreme positions — and drawn vehement protest rallies. This incident, of course, plays on advertisers' worst fears — and Facebook's.

Jason Calacanis, in search of a full-fledged strategy for his flailing "human search engine" Mahalo, wants you to work for him. For free. The wealthy Internet tycoon is using Linkedin to ask: "Lots of discussion as to the value of Facebook for startups.... wondering, how would you market Mahalo on Facebook?" Calacanis's Facebook bankruptcy has left the Internet millionaire downright poor — in ideas about how to use social networks, at any rate. Our favorite answer, after the jump.

In the youth culture of social networks, the worst thing to be is the old guy. Even News Corp. CEO Rupert Murdoch, after shelling out $580 million for MySpace, has tired of the website. And the Facebook frenzy could fade equally fast, if more people follow Jason Calacanis's lead and declare Facebook fatigue. That's why Plaxo has a shot — if a shaky one — at transforming itself from spammy address-book manager to the hot new thing, when it relaunches as a networking site on Monday.

With Facebook friends like these, who needs enemies? Noah Kagan, who left his job at the social network abruptly in mid-2006, now has a Facebook group in his honor: "Boycott Facebook until Noah Kagan is re-hired!" Valley prankster and Friendster founder Jonathan Abrams created the group. We pinged Kagan, who's now working happily at online personal-finance startup Mint.com and blogging at Okdork.com. Kagan, when pinged on IM, was as bemused as we were to hear about the group, but had no idea why Abrams was starting it a year after his departure. The Facebook group, however, might not be telling the whole story about the Facebooker's departure: A well-placed tipster says Kagan was fired for leaking company secrets to TechCrunch editor Michael Arrington.

What is it about the women Facebook hires? I'm sure they're all brilliant, but it needs to be said: The hot social network has equally hot personnel. Randi Jayne, sister of CEO Mark Zuckerberg, finally outs herself on video as a Facebook employee in this clip. But the video doesn't do her justice — as you might have noticed in her "Dontcha" iPhone video, she's distressingly cute. Her colleague, Meagan Marks, gives a sales pitch for working at Facebook that's best appreciated with the mute button on. And spokesperson Brandee Barker? Alas, she's not captured in this video, but you can check her out in this AllThingsD.com video. Or just take our word for it: Total babe.

Entrepreneur, programmer, man about town — if by "town," you mean "Palo Alto." That's our Dave McClure, part of the PayPal gang and now, in geek semi-retirement, an extreme fan of Facebook, the buzz-ridden social network. I've known Dave a long time, and respected his critical thinking skills (as well as his avid commenting on Valleywag). Which is why I've never understood why he joined right in the Valley's Facebook frenzy instead of standing back and, with all his experience, questioning the hype. For the answer, roll the tape.

Sarah Meyers, Valleywag's new videographer, attended Facebook's Lunch 2.0 happy hour and asked Facebookers and other developers what the buzz was all about. She cut through the hype to get the real answer on why Facebook's so hot — the long-rumored IPO, of course.

Facebook has been called "the Brangelina of tech" for its ability to mesmerize the Valley's press corps. Insiders at the red-hot social network don't want to believe it. But it's true. At last night's Lunch 2.0 event — a periodic gathering where Silicon Valley companies take turns serving up free food — Facebook showed off its inability to cope with its newfound popularity. Even the timing reflected the crush of interest in the event: Facebook's caterers declared themselves unable to accommodate the lunch crowd, so Facebook turned it into a happy-hour event instead. Facebook's undersized cafeteria was filled with developers, Facebook execs, and assorted hangers-on who packed themselves in like college freshmen at a kegger. Even ostensibly sober types like the Wall Street Journal's Vauhini Vara, shown here double-fisting beers, found themselves caught up in the frat-party atmosphere.

Rip up your Facebook revenue estimates and start over, everyone. Since February, Facebook has doubled the rates it charged for sponsored groups from $150,000 to $300,000. Since exposing Facebook's supposedly nonexistent rate card, I've received a more recent version from June. Much of it's the same, but I'm posting the revised cards from Facebook's PowerPoint deck, with comments, below.

Facebook appears to be having a privacy crisis. Earlier this morning, The Register reported that some people were able to see other Facebook users' private message inboxes. Blogger and IBM employee Matt Dibb reported Facebook exposing other people's email addresses on its login page. VentureBeat speculates that a bad update to Facebook's codebase got rolled out — and today's supposed "upgrade" was actually Facebook's panicked attempt to fix the problem. Since Facebook's fine-tuned privacy controls are a big selling point, this mucked-up code episode is especially embarrassing. Mark Zuckerberg, if you can take a break from counting your fictional billions of dollars, care to take a look at your site's code? Update: Facebook says it has fixed the problem. The statement, after the jump.

Forget Facebook fatigue: The new symptom sweeping the Valley is Facebook addiction. A brief outage this morning made most Valley workers more productive — but left some, like strung-out addicts, completely unable to function. One particularly sad case expressed his relief that Facebook was back up. "I've already forgotten the cold panic, the unbearable neediness," he wrote. Also left unable to function: Facebook's PR apparatus, which promised a statement about the outage that has yet to materialize. Perhaps spokeswoman Brandee Barker was hoping to send it out through the Facebook group she normally favors, instead of boring old email, for press releases?

Facebook has been down for most of the morning, ostensibly for an upgrade. Which is nonsense, of course. No well-run company updates its servers in the middle of the day; Facebook's unexpected outage can only be, well, an unexpected outage. But we can't wait to see what happens when Silicon Valley's entire workforce has to actually stop using Facebook and get something done.

"Wall Street's Best Facebook Analyst: Valleywag." So says Henry Blodget, who analyzes our discovery of Facebook's secret rate card. [Silicon Alley Insider]

Here's a new Facebook revenue estimate to think about: $90 million a year — from sponsorships alone. Sure, I've poked fun at Facebook's fanciful figures. The social network's board members, after all, can't get their stories straight on how much the company is making — so why should we trust their wild-eyed, multibillion-dollar valuations for the company, either? But now it gets real, folks. An informant has forwarded me a Facebook rate card — a rate card the company claims doesn't exist. It's dated February, so keep that in mind. And any rate card, of course, is a salesman's fantasy numbers, not the real ones that get hammered out in a sharp-elbowed deal. But the contents of the card square with what I've heard from insiders. After the jump, what it takes to buy your way onto Facebook.

People say that Facebook might be the new Microsoft as if that's a good thing. The Windows operating system, after all, has been an immensely profitable platform for third-party developers, and Facebook, with its F8 platform, hopes to do the same. But there's another side to Microsoft as platform owner — the side that willfully enters a software arena and destroys independent developers working in that market. That's the cruel face that Facebook is now presenting. Here's what it looks like.
