I know most times I might not say much during the fight, unless I got caught with a good combo/setup or someone did a great comeback, but during character select, and the other portions of the match where no real thinking is required I'll chat a bit... Sometimes though I will actually say something during the match, and that's dependant on what's actually going on... If I'm helping someone with a character, or if I just found out something, I might feel inclined to share the info during the match, because I'm not the type to keep information... If I'm spectating, I'll chat a bit though... If people don't really chat online, then hitting them up on the forums (provided they're signed up) is something I don't mind, as I find more people talk that way or over texting on xbl...
