It's a good Website to communicate with friends and stay in contact. Though, I think you need to have a good knowledge about the web and its dangers. Data security can be cared for but: By yourself!
If you don't know about general media structure, you really should get informed!
For this, I don't think kids should use it. It is not really suitable and they probably spread personal data in the world wide web.
Loosers get Spyware and post low raitings!
It is the Best social network at all
Everybody lies! don't truth to everything and you never fool
(and never get malicious soft!)
