Fans who quit comics no doubt read this board if only to keep up with artist/writer changes, spoilers and issue summaries.
I quit reading comics with the penultimate issue of Siege. There were still a couple books I was interested in, but it seemed like a bother to go buy the TPB.
I think it was Hylerstyle who had as his sig his pull list. Each really excellent book followed with the word "canceled." I know there are people on these boards who quit buying comic books because a) they were upset with a dollar price increase in a time of economic doldrums or b) they got sick of the hype about events or c) they woke up and realized they were 34 or d) Bendis sux.
This is not a poll, but a forum for other Marvel Zombies who relatively recently quit reading comcs.
