I don't understand the good ratings. Though it does not provide malware or viruses, it gives almost no privacy (or removes it without notice) nor child safety.
It was very good when it had come initially and later on the site started to loose its fame..But still there are lot many things that are doing fine..I too have lot of good experiences with it..
Beware of this site !
It's one of the biggest virus source ever, and in addittion, this site steal you personnal data to use it as they want.
So, stand away from it !
Good for social networking, although it's not only site geared to social networking. If you set the privacy settings appropriately and you use facebook wisely you shouldn't run into security issues. Parents be advised that some groups on facebook are probably not appropriate for your children. It can be time consuming as well, but overall it is a good site!
I like facebook. Like most other sites you have to be responsible to select & double-check your settings. And having a good security program installed.
