Tor has done a number of these rereads of popular series. You can find them all there in their archives. The way it works, a fan of the works in question rereads them, book by book and story by story, and posts their observations, and everyone else chimes in.
It's always fun, and often illuminating as well.
Katy Rask will be leading the reread for Wild Cards, and who better?
So get to reading! The first of March is almost here.
