Actually, on reflection, the better solution would have been to 86 some of the damn Robins. Does anyone really care about Jason Todd? And I like Tim Drake and Damian Wayne, but I'm not filled with a burning need for them to exist.
I read a comment the other day on some website to the effect that DC's relaunch shows how impatient and incapable they are of stoking enthusiasm. Ultimately, I think this is correct; the 52 different titles, and the everyone-exists-now! mentality is going to really damage how effective the relaunch will be. Not in terms of us nerds, since we're conditioned to put up with nonsense, but in terms of lapsed and new readers.
