I mix up both my online and live games.
I try to get to the local casinos
as much as possible and I have a once month live game (24-27 players).
The social aspect of the live games can't be beat.
I find it extremely hard to follow the chat windows, type a message and play my hand at the same time.
I like to follow the action on the table (both live and online)
Online poker is great for those late nights when you have nothing to do and want a quick 30-60 minutes of fun.
Don't get me wrong I have made some very good friends online playing poker (here at CC and other places) and I enjoy playing online in friends private tourneys.
All that being said, I'm still going to play online and I'm still going to go to the casino (Going to Vegas on the weekend of the 27th!!!)
