Usenix Open Access
I was going to pick up posting again and what better way to do that than to point to today's announcement by Usenix to open up the access to all of their conference proceedings. Compared to the IEEE Computer Society and the ACM, who still hide the published material behind the walls of their digital libraries, Usenix already had a very liberal one-year-members-only policy. But now their publications will be available for everyone, instantly.
I am a Usenix, ACM & IEEE member and will remain one, so it doesn't make much of a difference to me, but I believe all professional organizations would serve their members better by making their publications freely available to public.
