The other way around? So, you mean for the most part, DC characters let everyone know who they are? What the fuck?
Well, not everybody, but pretty much all the heroes knew who all the other heroes were. And there are a shitload of heroes.
On the other hand, over at Marvel even the Avengers didn't know many of each other's identities.
Englehart addressed this in his first run. Thor and Iron Man totally knew each others secret IDs, even though they pretended they didn't.
IIRC, the JLA first learned each others civilian IDs in JLofA #19. But I think they might have erased the memory of it.
