The British Ministry of Defence is worried about oversharing military personnel and their oversharing families, so they've created a few videos that should really make everyone think twice about careless tweets and Facebook status updates. In the video above, after checking in on Foursquare (which should be a crime in itself), the young sailors are seen dancing with scary terrorists who were tipped off to their location in a nightclub by stalking their profiles. So now they're all up in our Twitter, Facebook, Foursquare and probably even Myspace. That means no more tweets like, "I just disabled all security measures at ______ nuclear plant! LOL!" Ok?

Someone is aggressively hyping Facebook to the financial community. Investors are being told the social network's value will double in 12 months — and quadruple over 18 months — to $100 billion. It sounds like someone has shares to unload.

Mazel tov to Facebook founder Mark Zuckerberg and his longtime girlfriend, med student Priscilla "Cilla" Chan, who are engaged! According to Bill Gates, at least, who seemed to let the news slip during an interview with The Daily Mail:

Check out Mark Zuckerberg's fancy new stationery, featuring embossed paper that reads "FROM THE DESK OF MARK ZUCKERBERG, FOUNDER & CEO OF FACEBOOK." Ben Barry, a graphic designer who works at Facebook, explains its purpose:

Well, this is all extremely ironic. Here's a speech that Facebook chief Mark Zuckerberg gave yesterday to 8th graders graduating from the Belle Haven Community School in Menlo Park, California, the same city where Facebook's giant new headquarters will be located.

38-year-old David Voelkert thought he was chatting with a cute 17-year-old girl on Facebook about his plans to track down and kill his ex-wife. Turned out to be his ex-wife.

Earlier this week a strong contender for Dumbest Tattoo of the Year appeared in a video, My Social Tattoo, that depicted a woman with the profile pictures of 152 Facebook friends tattooed up her arm. Sadly, it's fake:

Another day, another Weiner cybergirlfriend. Meet Traci Nobles of Athens, Ga., whose roommate, against Nobles' wishes, emailed journalists "a private [Facebook] conversation between Weiner and Nobles." (It's more flirty than sexy). Nobles wouldn't provide more information. [LVS]

You remember when Facebook rolled out its creepy facial recognition technology last December in the U.S. Now it's available worldwide. Let's point and laugh as Europe freaks out about the same thing we did six months ago.

In a tearful statement to the media, Rep. Anthony Weiner this afternoon admitted he posted a picture of his own dick to Twitter. Not only that, he says he's engaged in "inappropriate" online communications with at least six other women.

A German teenager named Thessa forgot to make sure the Facebook "event" for her 16th birthday was set to private. So 15,000 people confirmed their attendance, and more than 1,500 showed up on her doorstep.

Remember the four-month-old fetus whose parents gave her a Facebook page, for some reason? Little Marriah's page has been shut down, probably because Facebook doesn't allow kids under 13 (and maybe also because her parents misspelled "Mariah").

Since being portrayed as a hard-partying tech playboy by Justin Timberlake in the Social Network, it has become impossible for Napster founder Sean Parker to have a party that is not a crazy blowout because of his new reputation. He tells the Post:

It's all a forgery, Mark Zuckerberg says. The contract where he signs over Facebook ownership; the emails where he tries to swindle his business partner — all fakes from a known liar. Once a liar always a liar, right, Mark?

Facebook has been taking heat for letting kids under 13 use Facebook. So, people should be absolutely freaking out about this four-month-old fetus whose parents signed her up on Facebook and friended dozens of people.

Eric Schmidt is sorry he let Facebook walk away with the entire social networking market. The Google chairman and CEO said he knew about the threat several years ago, but didn't address it. Distracted, much?

Announcing herself this morning on the dual social networking platforms of Facebook and Twitter, pulsating cloud of wishes and light Gwyneth Paltrow has come roaring into the 21st century, ready to conquer the new media world just as she did country music.

Facebook is reportedly close to adding its 700 millionth user, indicating that the social network is on track to cross the billion person mark sometime in 2012. Good luck catching up, Google.

New Zealand PM John Key apparently doesn't mind the deadly, coma-inducing Australasian internet craze called planking. In fact, he supports it. In a picture posted to the Facebook group Planking New Zealand over the weekend, his son Max is seen planking in the premier's residence under the watchful eyes of his father. Just what kind of message is John Key sending to the youth of his nation?

Mark Zuckerberg has begun personally slaying animals for food, part of a resolution to fully appreciate the meat he eats. The Facebook CEO's slaughter has been wide ranging, claiming a goat, pig, chicken and a lobster.
