Publishers may be okay at the moment, but I still think they're doomed. There's literally no barrier to entry in the publishing business, which is eventually going to break their pricing cartel.
As a reader without unlimited time the publishing industry acts as a barrier to entry which filters out the worst books... We need a robust reviewing system which filters out shill reviews.
Why should I waste time on this? I know that books in the SciFi section of my local bookshop will have a certain minimum standard without needing to wade through some reviews.
You have a better local bookstore than I do. Mine is all Star Wars expanded universe dreck (last decade or so, in prequel land or tying into a children's cartoon), Star Trek fan-fiction, Halo novelizations, etc. With some classic Asimov, Clarke, Heinlein, Bova, and a very few other authors thrown in to class up the joint, although usually just the more well-known titles I've already read.
