As much as I find some of their choices over the past few years rather dubious, DC does have a great rep for putting out some different ideas on the market - Like the 'Black and White' Batman books, which were pretty good and gave us some top-notch creators on the most prominent character in the medium, and Solo, which was an excellent book just purely because of the idea - Top creators doing work on whatever they wanted.
Of course, those books and Wednesday Comics were all the brainchild of one guy, so I hope that Mark Chiarello really gets his reward for these ideas.
