I think there needs to be a wiki out there that chronicles every superhero (and their iterations) so people can go to it for reference or fun. I tried to make one, but I never really promoted it. It's still on wikia, languishing. Maybe this is me promoting it. Just I'm not giving the address unless people want it.
But what I don't like about the Handbooks is how quickly they go out of date. It's inevitable, but still annoying.
