Wondering what you've given a try (series, story-arc, Graphic Novel, whatever.) that you wouldn't have if not for the input from Comic-Vine. Be it from reviews or just chatting around. For me, I would have never read:
Green Arrow: Year One (Which Rocked!)
Dogs of War. (Hulk story arc that was very good)
I just go my first TPBs of "X-O Manowar" and "Invincible", because the comments on here about those series peaked my curiosity.
