Check over on xda, that's where he and the other devs spend most of their time. But he has given us quite alot in a very short period of time. Debloated stock ROM's for those who prefer that, the most functional CWM we've seen yet, his awesome PBJ kernel with jt's voodoo, and one with the OC/UV source built-in. That's pretty awesome, and already his kernels run as stable as the stock one, but a good bit quicker. All I'm really looking for at this point is fixing the boot animation and maybe a faster boot-up, improved stability (if possible), and maybe voodoo color (though its not nearly as necessary with S-AMOLED+).
But with us likely to hear something about GB any day now, I wouldn't want him to get burned out working on Froyo kernels, I'd rather wait and have a full-featured GB kernel with the VZW spyware ripped out right off the bat!
Still though, mad props to him for everything he's done.
