I'm more of a casual fan. I don't buy anything monthly, but I have a few series I've collected.
Preacher, Sin City, most of Garth Ennis' Punisher stuff (Knights/MAX), select Batman collections, The Darkness, Bone, a decent chunk of Civil War. Not too big into the monthly superhero stuff.
Just started reading some comics on my Kindle Fire...already read Batman: Year One...have read most of Watchmen in a day...ordered a physical copy of Maus
I enjoy comics...ever since I was a kid back in the early 60s. I still buy comics, but as nice as the new graphics look good I still prefer the old style graphics.
At a conservative estimate I have 800 graphic novels and 2500 comics. Mostly DC and indie - Marvel crossovers put me off trying to keep up with their stuff.
The RAD pales in comparison
Currently reading DC Bomnshells v1 and Midnighter, with Locke and Key master edition v1 and Transmetropolitan absolute queued up next.
