What horror stories have you heard about or perhaps even happened to you as a result of information that was posted to blogs or social networking sites such as MySpace and Facebook?

One of the worst that I've heard was from a friend of mine who was hiring a technology sales representative. He ran a Google search on her name after he and everyone else at his firm had decided they wanted to hire her. Although she had been careful not to include her name on her page, her friends weren't so smart and created a link from her name on their pages to the candidate's MySpace profile page. Google is smart enough to have understood that although the candidate's MySpace page didn't have her name on it, because her friends linked using her name that people searching for the candidate by name will want to go to the candidate's MySpace page.

The problem wasn't that she had a MySpace page. The problem was that the content indicated that she likes to get drunk and have sex with strangers. My friend declined to extend the job offer to her not because of that (he doubted she'd get drunk and have sex while on the job) but because her posting of that information on-line indicated a lack of good judgment.
