The best collection of academic blogs I've yet seen is the Academic Blog Portal. Better yet, it's a wiki, so it has a chance of growing as large as it takes and staying up to date. Add your own! (Thanks to Steven Bell.)

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.
