I go for a couple reasons the streamer if they're a -blam!-ing good entertainer they'll be able to keep me around, the chat think of it like the forums except the mods are there because they wanna be there too and it can get pretty hilarious in there. The other reason usually I found the streamer through youtube and went to twitch to watch more of their content that they do not put on youtube saavy? Its a timewasting thing when I dont wanna read a book play games or much else and just wanna relax and have an interactive laugh with a load of other people but likee the other guy said its not for everyone :)
