Wendi Deng, the wife of media mogul, Rupert Murdoch, is impersonated with a verified Twitter account. This and more in today's Daily Wrap.

Sometimes it's difficult to catch every story that hits tech media in a day, so we wrap up some of the most talked about stories. We give you a daily recap of what you missed in the ReadWriteWeb Community, including a link to some of the most popular discussions in our offsite communities on Twitter, Facebook, LinkedIn and Google+ as well.

Rupert Murdoch joined Twitter last week. So did his wife, Wendi Deng Murdoch. "Joining my husband @rupertmurdoch in our new digital adventure on Twitter," reads her bio. Cute, right? Rupert was verified, Wendi was verified, and so began another cute chapter of celebrities figuring out how to use Twitter.

Much to the world's surprise - and inability to cope - Rupert turns out to be pretty good at Twitter. You know who's even better, though? Wendi. She's so good, she convinced Twitter and News International to verify her account, even though, as she admitted today, she is a fake. Twitter didn't even ask her, and News International thought it was legit. The account is no longer verified, but it was for a whole day.

The Washington Post launched a new app Tuesday aimed at tracking mentions of presidential candidates on Twitter.

@MentionMachine was developed exclusively for the newspaper and was launched in conjunction with Tuesday's Iowa Caucus, the official start of primary season for the 2012 Presidential Election. The app uses Twitter's streaming API while also tracking mentions in the traditional media.

The launch of @MentionMachine is telling, in that it formally adds "social media success" to polling data, fundraising totals, ad spending and endorsements as ways to measure how well, or how poorly, a campaign is doing. For those keeping score, Ron Paul had the most mentions in the 24 hours preceding this writing, with 44,900 tweets.

The answer is to moderate our use of and dependence on social media, especially Facebook.

Frictionless sharing, the act of passively notifying social media of all manner of activity, scares the hell out of me. Not just because of the obvious privacy implications. Frictionless sharing turns up the volume on useless information and simultaneously threatens user privacy and control of online identity. Not only is Facebook becoming too central to our online discourse, it's becoming too crapified to even be useful. We have a social media problem, and the time to turn back is now. And the answer isn't regulating Facebook.

Twitter appears to have forwarded a subpoena requesting user information to at least one of the owners of the accounts in question, despite a request from the Suffolk Massachusetts District Attorney's office that the request not be disclosed "to protect the confidentiality and integrity of the ongoing criminal action" regarding the hackitivist group Anonymous and events surrounding the Occupy Boston protest.

"Haha. Boston PD submitted to Twitter for my information. Lololol? For what? Posting info pulled from public domains? #comeatmebro," said the owner of the Twitter handle @p0isAn0N last week, in a post that included the subpoena. The subpoena also sought user information, including IP addresses for @OccupBoston, Guido Fawkes (there are more than 30 accounts using the name Guido Fawkes on Twitter) and subscriber information for the hash tage #BostonPD.

Earlier this fall, a judge ruled that a lawsuit filed by PhoneDog.com against one of its long-departed employees, Noah Kravitz, has merit. According to Eric Goldman's Technology and Marketing Law Blog, the company is suing Kravitz over three points, including trade secrets and misappropriation of the account. The ruling, reported by Goldman and the New York Times, states that Kravitz is liable for several hundred thousand dollars in damages, calculated at $2.50 per month per Twitter follower.

This isn't the first conflict over who owns your Twitter account, and it certainly won't be the last. When Rick Sanchez left CNN he kept his account but changed the name. This is what Kravitz did when he left PhoneDog.

Chris Poole delivered the most powerful 10 minutes of Web philosophy of the afternoon at Web 2.0. The man formerly known as moot - founder of anonymous image sharing den 4chan and its new, better-lit cousin, Canvas, gave us a rousing and principled picture of what the big players get wrong about online identity.

"Google and Facebook would have you believe that you're a mirror," he said, "but in fact, we're more like diamonds." - multi-faceted. It was an appeal reminiscent of the one he gave at SXSW earlier this year, but it hit harder. Google Plus has since arrived, and Poole says it's even worse than Facebook for the future of online identity.

The takeaway from an MIT study released Wednesday, tracking the early growth of Twitter, is that new Web technologies - particularly social networks that rely on adoption by other users - cannot depend solely on online buzz (or even Ashton Kutcher, for that matter).

The study tracked data from 2006 to 2009 in the 408 U.S. cities with the highest rates of Twitter adoption. The findings clearly demonstrate that mainstream media mentions, coupled with the geographic and socioeconomic proximity of users, fueled its growth. A video mapping the data shows initial growth in San Francisco, where Twitter is based, then spreading to Boston.

A Swedish charity is claiming a first after setting up a paywall on Twitter in which people pay to read Tweets from some of the country's celebrities.

Author Susanna Alakoski, pop singer Niklas Strömstedt, music journalist Fredrik Strage, director and actor Felix Tobias Herngren and television host Gry Forssell are among 15 noted Swedes who have spent the past week Tweeting for Stockholms Stadsmission, a charity that focuses on homelessness in the Swedish capital. More than 500 people have forked over the equivalent of $4 U.S. to follow the celebrities in the fundraiser, which ends Wednesday.

The New York Times is reporting that U.S. officials are considering legal actions to shut down the Twitter account of the Shabab militant group of Somalia.

Noted for its brutality, the Islamic group is considered a terrorist organization by the U.S. The group has been using its Twitter account to taunt the Kenyan military, which was dispatched to Somalia in October to combat the Shabab.

Any such move to pressure Twitter to close the account, however, would pit free speech concerns against anti-terrorism efforts. "I was kind of shocked by the statement that story was making - I honestly thought it was a joke when I first saw it," said Joshua King, general counsel at Avvo.com. "There's really no legal authority they can use in this instance."
