During a 6 hour tournament sometimes its fun to chat, especially when people are dodl'ing and waiting the clock. I've had some fun conversations with random people, and fun arguments. I've also had people send friends invites afterwards.
There are a few people who I expect to see at some weekly games on specific sites.
If you don't like chat, I am fairly certain
unibet has no chat in game.
Sportsbetting allows chat even in all-in situations which I like, while Ironpoker and
pokerstars and Full tilt dont allow it I think.
freerolls - Sometimes you can use the chat to get everyone to go all in on a hand, if you win it there's a decent chance of getting past the bubble
