Any personal information posted to the Web can be twisted to suit the agenda of the narrow-minded. If you post a photo of your puppy on Myspace it opens the posibility that someone is going to call you a cat hater. It's not a logical conclusion, but since when have people behaved logically?

Don't give 'em a chance to use their illogic against you. Keep all personal information that could remotely be construed as "dirty laundry" off the Internet.
