The Marvel Oversized HC and Omni thread alone (and keep in mind that this is a thread that bans discussion of the most popular format: The Trade Paperback) has over 13,000 posts in the last year or so. A SINGLE thread that excludes the most popular collected format has THAT many posts (and that's AFTER a mod cleared out the chaff). That's not even counting the other mega threads.
I don't think you guys understand just how popular collected editions are. Maybe you should hop on Amazon.com and see just how many hundreds of these puppies are released every year.
Even if only half of the released collections had threads about them per year, you'd also have discussions about great deals, wishlists and speculation on future collections, collection pics thread, binding type discussion, binding your own floppies into your own hardcovers discussion, it just goes on and on. This isn't speculation on my part, these conversations are already happening and would be much more user friendly and robust if they were allowed to breathe, not to mention attract more people who at this point are intimidated by the 13,000 post thread and don't know where to begin.
So yeah Mr. Incredulous: REALLY.
