well, if you still got the time, you can pick up something now to start tinkering with. if you listen around for a bit you might start picking up what peoples hobbies are. (lots of people do 3d stuff obviously for avatars). then pickup something you actually like and share your learning experiences. remember to help guide the person your talking to, because some will just assume your asking for help (newfags always show up asking how to get their boobas to work etc). 
Or to put it simpler, don't have anything to talk about? go out and experience something, come back with that. It doesn't have to be as daunting as it might sound.
