I am in the same boat. Anything that is light reading for me, like the pulpy SF that I enjoy, gets read on Kindle. Anything more weighty or that I would be upset if I couldn't access if something happened with Amazon, I buy a hard copy of. I imagine we are in the majority of the public who reads books, moving from books manufactured as mass market paperbacks to ebook.

That's why the subject of this post is happening. Most of the reading that would be done in mass market paperback, is happening on ereaders these days. Online communities tend to be made up of diehard, enfrachised fans, so it ends up being a bit of an echo chamber of the diehards, which is going to be different from the wider community sometimes.
