Well, online I chat a lot whenever there's people that are willing to chat.
The one aspect of live play I prefer over online is because I can interact with people and talk to them about anything that comes up for discussion. I love talking with people and getting to know exactly what type of person they are. Whether they're nice, an ass*hole, rich, poor, college student, long time poker player, recently picked up the game, ect, I use everything and anything that'll help me analyze what type of player they are and I use anything I can to my advantage at the table.
Don't get me wrong, I love talking to people and getting to know them to, I'm just a very social person on the poker tables, but I'm not just doing this for entertainment. I do it with a purpose, the entertainment is just a bonus.
