I have roughly $40K worth of comics in the house, most of which are in bags. Last time I bought a comic? Maybe 2003? 2005? Somewhere in there. I think the very last comic I purchased in a comic store was one of the Walking dead comics, back when they were the hot new thing. Used stuff ain't selling either, so I intend to hold onto it for a while then figure out whether to pulp it, decorate with it or find some nerds and give it to them.
Why did I stop? World of Warcraft. Team Fortress 2. Got a real job. Ran out of time to give a shit about comics, honestly. I've not seen any of the Avenger's movies, not seen the new Batmans. I have too much other nonsense going on. My generation bought a ton of comics and I wonder how many other people my age are in the same boat.
