I wish to recommend to you Hans Economics, a blog which promises to "save economics one post at a time." It's writers are bright and savvy economics majors here at Grove City College. The blog is less than two months old and already includes some very intelligent commentary.
The Hans referred to in the blog title is Hans Sennholz, long time professor of economics at Grove City College, and one of only four students to receive a PhD under Ludwig von Mises. Do not be surprised, consequently, if the economics of the blog has a decidedly Austrian, causal-realist flavor.
Hans Economics looks very promising and I am happy to add it to my list of Blogs of Interest.
