I'm one of the people who likes on-forum game threads. Because I'm out of state, busy, and unable to justify paying for Hoopstreams just for myself, I easily lose track of the schedule. I often don't even remember there was a game until I see the thread up on the board.
I feel like moving the game conversations into a venue where there's no archive for people to read afterwards would make it more difficult for people like me to keep in touch with what's going on. I'm lucky that I can usually catch nationally broadcast games (also thanks to the reminders on this board).
EDIT: In short, if game discussion is moved into chat, I would really appreciate it if someone could copy/paste the discussion into a forum thread afterward so that the latecomers and such can read it. As has already been suggested.
