I've played hold 'em on facebook before, personally I don't think it's as good as the poker that we have here, I like the feel of what we have here, I'd be up to play sometime, I want to play poker here some more I miss it.
I just played on Facebook for the first time. Did a tournament and won it. Most of the people were idiots. Several of them went all in on the first hand, so one chick had like six times as many chips as me right from the beginning. Ended up going heads up against her. After I took the lead she went all in pre flop literally every hand. I just kept folding until I got decent cards, then called and won.
Hopefully the Level 2 tournament will have some better players.
I've never used it and I don't plan to. I only use Facebook for keeping in contact with people. I've never felt the urge to play games with them. I don't even have any Facebook applications enabled. I'm boring I guess but that's why I go to sites like GF. Free times is better spent here than Facebook if you ask me.
