Certain Doubts Epistemology Blog
Although I'm sure they're just using the same template, regular TGGP readers will feel like he's been ripped off looking at this blog. I read a few of the most recent posts, they seem well-networked in the world of academic epistemology (the blog is full of conference announcements).
Still, one gets the sense the some of the post authors might be on the Igon Value side of quantitative literacy. Overall, it reads like a less muscular, less broadly literate version of the discussions going on at sites like less wrong and overcoming bias.
I ran into it simply by doing a google search for "epistemology blogs" and clicking on the first link.
