I have an account and a group. The site interface is not great, but I'm pretty sure they will be making changes soon since membership is growing rapidly.

The site is great to create a network of people and as you join groups and add people as friends you just get more and more involved.

I personally do not like the interface, because your Facebook page is made up of your friends. You can control the content some what, and minimize how much you want to show from your network, but you do not have total control.

Also I read an article on the advertising and they are experimenting more with it and trying to make better revenue for the site itself.

I have talked to a few people and for social networking it is a great tool.

There are also games and little image gifts and things you can send to people.
