Dave's a workin'.
If you're subscribed to the roller-cvs mailing list - you can see that Dave is checking in stuff like a madman tonight! I think that's how most open source projects are successful - one guy writes it, works his butt off and everyone else tags along for the ride. Am I wrong? Let me know - but that seems to be how Struts got started by Craig. Notice that I said started - it's not how it is today.
