what you think about Facebook (or these kind of social networking sites like Twitter,Orkut)?

[Anuj]

i m asking you that because,i hear that on these networking sites our private information and information setting and privacy are not secure enough..i know about how to make setting in these sites,but is that not enough?

i m asking these question not only for Facebook ..but also for Twitter (because last week twitter also facing some problem when user loose there follower's list and information)?
