There's a good discussion thread on the Taxacom list. It starts with the Max Planck Society's cancellation of 1,200 Springer journals and moves on to OA journals, impact factors, and what researchers and their institutions can do to help the cause. (Thanks to Napoleon Miradon.)

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
