Private myspace profiles and private facebook pages
Stupid ! Stupid! Stupid!
If you want to be private, don't have an account on a website that is used by over one hundred million people - keep in contact with your friends in other ways. But, having an account, joining groups, sending messages and, even, starting groups on topics of interest, and still being "private" is deceitful and dishonest. Be open, or sod off.
