I'm a lapsed fan. I buy comics irregurarly, mostly independent stuff from Vertigo, Image, vaarious Manga, some Marvel/DC.
I've read all the big titles in the past, but the new 52 drew me back in. What turned me off in the past is these mega events that have no lasting repercussions, or the changes are quickly retconned. The smaller stuff can have lasting changes, but the bigger stuff has to handle their properties differently.
Also, not really a continuity issue, but I like titles that have a definitive beginning and end, not where the comic began some time ago and writers
really have nothing new to add to the character but just keep it going.
Something I don't understand is once comic companies find a character that
sells well, they want to market them to death. How many comics can Wolverine/Deadpool/Superman/Batman appear in one month...? but I'm optimistic about Dc's future.
