First, updates are coming in a little bit at a time and you won't see much activity since many folks have tested all there is to do, to a point where smashing head against wall may seem more appealing.
Secondly, general chat is limited in distance so even if many folks are in game, if they are not near you they will not see you chat.
I haven't been on much as I recently bought a new game and toying around with that, but I'll be back after the next big thing is added to test some more.
