The DM in this game is just that good. He's an artist when it comes to scene settings and descriptive text. Definitely worth the wait.
The game I'm running on ENWorld has been running for about two and a half years as well, though more than 24 hours have passed. Actually, now that I think about it.. not much more than 24. Maybe 48? Anyway...
I've thought about moving that game into the CWBP several times, and am working in that direction... just taking a bit to get it there. In any case, if someone here wants to run a pbp game, I'm certainly interested in playing. I'd be willing to DM a D&D 4e game somewhere, but I won't promise that it'll move fast.
