i think it would make communication between the members of this community just a bit more human actually, on chat people tend to ignore you and talk about their own stuff in one big cluster fuck, the different channels for certain topics would actually organize things MUCH better than the current crappy chat room.
Definitely all for it, and im willing to bet that those that arent just dont want anyone to hear their little manchild voices L0l :P
btw; vent > mumble
much less ability to spam on vent imo therefore its better
