Welcome back, ladies.

In a fundraising effort on World AIDS day (Decmber 1st), several celebrity tweeters including Lady Gaga, Kim Kardashian, Alicia Keys, Daphne Guiness, Justin Timberlake and Jennifer Hudson declared themselves digitally dead until $1 million was raised to support Keep a Child Alive, a charity that provides food and medical care to children with AIDS in Africa and India.

Usher jumped the gun with 4 tweets this weekend {Dlisted} but as of today the campaign hit the target goal of $1 million.

Lots of people thought the digital silent treatment was a strange way to go, and in fact half of the $1 million was donated by billionaire Stewart Rahr.

Gawker wondered if Kim Kardashian would stay off of Twitter forever, and while celebrity tweets have been assigned a commercial value, it didn’t seem like many people wanted them back enough to pay for the privilege – even if doing so would support a worthwhile cause. As much as we can joke about the uselessness of most tweets, it probably didn’t help that the stars couldn’t tweet to remind their followers to contribute.

Twitter may not have proven to be the biggest bargaining chip when it comes to fundraising, but $500,000 in 6 days (the amount fans donated before Rahr’s contribution) isn’t insignificant.
