I already posted this at the DCU MB.
Here's an interesting article at Newsarama's blog: http://blog.newsarama.com/2009/04/24/line-by-line-trimming-the-pull-list/
Reading through all the replies to the article, it's noticeable how much the price increase has influenced on so many readers to start being more selective in what they buy, and start dropping titles.
In my own case, I always made sure to be careful as to spend too much on comics, so if I drop a title it's mostly based on how entertained I'm being by it, rather than how it costs. I preffer paying more for a title I enjoy rather than paying anything for a title I don't care for. But that's me. How about you?
