I have had a Google Wave Developer account for a few weeks now, but haven’t had the time to start developing with it.  Soon though.  Anyway, the point I was going to make is that recently a coworker just also got his account and he’s the first person I’ve had a live conversation with and well… it’s just fun. Yes, there are bugs and some of them are down right annoying, but once you get past those, the system really is just fun to play with.
