This is more Bora's thing than mine, but I should note that the new open access journal PMC Physics A has published their first articles as freely available PDF's. They also have a video interview with the editor up on the site.
Of course, with titles like "Dilaton and off-shell (non-critical string) effects in Boltzmann equation for species abundances," I'm not likely to be reading (or understanding) this particular journal much. But that's OK, they have an AMO physics journal coming soon, and if you act quickly, they'll publish your paper for free (submit by December 1).
They also have the obligatory blog, just in case you thought they were missing some new media element.
I am a big fan of open access everything. I get that some will make money and that some paid journals still have the most prestige today, and that's fine, but Heather Piwowar did a study showing that 48% percent of the papers that made their data public received 85% of the resulting citations. Lots of citations mean publicity and perhaps promotion, etc.
So the world is moving in the right direction.
