aesir23's thread (linked by (E)) is the best and most comprehensive so far.
There's also a slew of Green Lantern and Superman threads out there, and I started a
Wonder Woman thread a week or two before the movie hit the theatres.
To my knowledge, however, no one's done a comprehensive Justice League + Titans + Outsiders + Doom Patrol + Justice Society + Infinity, Inc + others thread covering all the major titles.
