It's different things for different people. Lots of us just like to read - pick up some viewpoints here and there, enjoy the images in IotD... for others... well, we can't keep our mouths shut (or our fingers off the keyboards). Personally, I imagine that if you stick around, you'll find an area (or people) that you're comfortable with. That's one of the really great things about the Cellar - there's something for [pretty much] everyone.
Anyway... hope you enjoy your stay, be it a week, a year, a decade...
and don't mind Nic Name. He does that to everyone.
