I consider myself somewhat of a comics expert. Looking at my reading history, virtually all I know is from the big two. Recently, I've been reading and really enjoying things like Invincible, The Walking Dead, and a couple of others.
Anyway, I just subscribed to Comixology Unlimited. It's basically a Netflix of digital comic books. Unfortunately (or maybe fortunately since I need to diversify my reading) it has nothing from Marvel or DC. Any recommendations?
