Same here. A few years ago I didn't even pay attention to other publishers outside the big two. Now I rarely pay attention to DC.
Well, I'm not quite there yet... but I'm getting there. I left comic collecting in 1999 and only came back about a year ago. I had always been a huge DC buff, so of course when I started, once I settled on a pull list after a few months (of 10 titles -- I always stop at 10 just because more than that is insane to me), it was 100% (10/10) DC. Now it is 5 DC, 1 Marvel, 2 Image, 1 Dynamite, 1 Vertigo (so if you count Vertigo as DC, they make up 60% of the pull list). And I would not be surprised if by year's end that number is halved.
