Re: OA publishing
I believe that they also get reviewers to review submitted articles for free too. The business model for academic publishing seems to be highly profitable, except that no one seems to be able to break into it with a more equitable arrangement and maintain the quality of content. Maybe academics should start a union or something?
(Mind you, it is not foolproof, I understand the editor of Nature rejected a paper outlining the Polymerase Chain reaction. And 'The Lancet' published that anti-vaccine article on MMR, fallaciously linking it to Autism.)
