I'm so disgusted with it that I canceled my account. It kept sending emails to people with my name that I didn't send or approve. And when I first signed up for the account, I specified a few people that I wanted to "invite" and it invited my entire contact list!
You guys know that contacts lists remember everything, from the person you emailed once about a Craig's List ad to the Girl Scout Yahoo group. Plus, I seem to have most of our church congregation in my Contacts because I was VBS Director last year. People keep coming up to me at church and telling me, "I got your FB invite..." How embarrassing!!!
I did catch up with a couple old friends, but other than that, the only useful part of it was the long distance Scrabble that my mom and I could play.
So I wash my hands of FB completely.
