I did hit 80 too, sometime early December. I haven't done any raiding or instances, usually because I'm either playing with just a short amount of time, or because the group doesn't want/need an enhancement shaman (and I'm stubborn enough that I won't respec from the talent that I've used since level 10). I've spent the time since hitting 80 working on achievements and leveling alts. Eventually, the rest of my guild will (hopefully) catch up with me, and then the plan is for us to recruit heavily and start raiding.
