"Everyone's gotta learn to make their profiles on these type of sites private. "  I could not agree more.  I used to keep my MySpace profile open until someone I know locally who turned out to be a psycho.  I didn't put anything skanky on there but I didn't want her knowing what I was up to in my life so I closed it down.  I'm now over at Facebook and keep that private as well. 

I'm always totally amazed at the stuff people put on their social networking pages.  My DH's niece who is 18 has the nastiest stuff on there.  She'd probably spin around thrice and drop dead if she knew me and her uncle were reading her nasty crap.  It literally makes me sick to see the stuff she and her friends say.
