For my reference: some blogging directories/sites mentioned on Humanist:
Technorati is a pretty amazing gateway to blogs: http://
Crooked Timber’s academic blogroll
Jill Walker’s jilltxt.net, specifically the following entry categories:
Blogs and Teaching
And her Bloglines feed
Also her article “Blogging Thoughts”, co-written with Torill Mortensen, in which she discusses the use of blogs as an online research tool.
Finally, she has an older list of research weblogs.
