Celebrity philanthropists from all over the country are jumping on the social networking bandwagon, raising money for causes they care about on site like Twitter, Facebook, and LinkedIn.

One of the biggest names to use his online popularity to increase charity donations is Pittsburgh Steelers safety Troy Polamalu. The NFL superstar recently sought to capitalize on his 106,000 Twitter followers by auctioning off a chance to be mentioned in a tweet, the Pittsburgh Tribune-Review reports. Proceeds from the Twitter mention will go toward helping military veterans, those who are currently serving and their families.

"The people who serve our country are the least provided for now when they do everything for us," said the NFL player's wife, Theodora, in an interview with the paper. "That's why I feel so strongly about helping veterans."

Other big names have been making news by using social networks to raise money for a good cause. Former American Idol contestant Adam Lambert is also using Twitter to help raise money for a clean drinking water charity.
