I do not use nor plan to use any Ebbron content or adventures in my game.
That said, i think that wizards is putting too much effort in to it and ignoring thier other campaign worlds. I have been playing for 20+years and have used grayhawk as a source for my own worlds and as it was intended to be used. Nothing compares to the classic world of Grayhawk.
I am also a member of the RPGA and think it really sucks that Living grayhawk is getting ignored in favor of Mark of Heroes (ebbron).
my 2 coppers worth.
