We might like to think that information-sharing is intrinsic to academic work, especially academic work that is publicly funded. However we also place many restrictions on publishing, like peer review, and I imagine there are still academics who try to keep their work secret until it is ready for any number of semi-paranoid reasons. I'm not going to say we shouldn't do these things, but we need to recognize that the discipline works by controlling the production and distribution of disciplinary knowledge.
