Scientific publishers (as it stands) provide 3 services (publishing, filtering, accreditation) - these could be decoupled and that is what PLOS One, PeerJ and other folks working on "alternative" metrics of evaluation for scientific publishing are pushing for. If pusblishers really only did publishing we would be putting our papers in blogs. It is very very frustrating that it is taking so long to decouple those functions and to have true publishing systems that are as cheap as blog hosting with services on top that are open for competition.
