I noticed that if you timeout while having to put in a blind, you're kicked from the table. But when you timeout while you have to fold/check/call/raise, you just fold and remain at the table. Earlier today, I played some poker when one of the people repeatedly timed out. It wasn't until he was left of the dealer he got kicked.

IMO, it would be nicer for the other people if a timeout means the player gets kicked - he/she can always rejoin if she/he returns to the screen.
