I asked the proprietor of Economics Roundtable -- an excellent aggregator of economics blogs -- whether he would include this site in his aggregation. But alas, he thinks we have too much non-economics to allow us on, and therefore I need categories so he can pull the econ stuff out from the non-econ stuff. I've looked a couple of options for this to use with Blogger, which doesn't have categories naturally built in. They are mostly kludgy hacks with using del.icio.us or echoing blogs. What I'd like is something that would allow me to pull down a category list. Ideas appreciated.
