I think one of the reasons for the slowdown in previous years is due to the start of other threads such as "Latest Orders" and "What collected edition are you reading", not to mention "Good Deals" which started a couple of years ago. So what we used to post on this thread is now posted elsewhere.
I don't think the "single issue" game that Marvel is playing is the reason. In fact, it's probably the opposite as I for one stopped purchasing singles a couple of years sgo and only pick up the occasional "special" issue.
