Firstly I would like to point out that Facebook is not a Chat room lol, some people dont seem to realise this, also facebook has no chat rooms incorporated into it and they have no plans to !
Facebook is a community site, its a very good site, I do however have problems with it, there are serious security issues, with the biggest crime at the moment being identity theft, then Facebook is going to be heaven for these people, as its possible to find out many details about the people on there.
I was listening to the radio recently apparently Facebook is costing Uk employers millions of pounds as all their workers are logging onto Facebook instead of doing their work lol.
So I think its just a matter of time before employers start blocking this site, which might see a decrease in Facebooks popularity.
World of chat also has a group on Facebook, I have created this to try to get people to visit our chat rooms, so if you are on there please join our group.
