I don't feel like there's too much DC talk, but in fairness, I would agree that if seems like there is, it's mainly because DC has given more to be discussed than Marvel. With the launch of the New 52, it's just simple mathematics that there would be more to discuss than the (mostly) same old same old from Marvel.
Like a lot of you on the show at CGS, I find myself in the same boat of not really reading/buying much from Marvel - as there just hasn't been much they've put out that interests me. Over the last 5 to 10 years, I've found the number of Marvel titles I've been getting dropping down to just two - Thunderbolts (which I've bought since it's inception), and Daredevil (which I've gotten since the Kevin Smith relaunch). Both of these books continue to preform for me, while everything else has just fallen by the wayside.
With DC, on the other hand, I'm currently reading over a dozen titles.
As for indie stuff, even then I find I usually only buy what interests me, and again, that isn't much. Right now it's Buffy from Dark Horse and the Planet of the Apes titles (particularly the mini series) that Boom has put out.
Granted, another big factor is also money. There's plenty more I'd like to be able to read/buy, but these days, I simply can't afford it.
