Yesterday (10/28/2010), the American Geophysical Union launched a new science blogging network, the AGU Blogosphere.
Similar to PLoS Blogs, the AGU Blogosphere does not run external ads (though they reserve the right to run AGU-related ads on the home page and on staff/guest blogs).
Focusing primarily on earth and space science, the AGU Blogosphere has an impressive lineup of bloggers. Please support their new endeavor by stopping by their new site!
