Does anyone know why there's not a free pre-print server (http://arxiv.org/) in other areas of science? It's the morning paper of most theoretical physicists, big papers get published there first (and in Nature, Science second), or even Fields medal winners publish only in the arxiv and avoid journals. Why hasn't this happened in other disciplines? Is it lack of LaTeX knowledge? critical mass? ... I've always wondered.
