Michael's pointer to the JSP post raises an issue, and some questions. There are a lot of blogs, far too many to read all of them. Of the ones on the ELS blogroll, I regularly keep an eye on only Balkinization, Prawfsblawg, and Volokh, with an occasional voyeuristic peek at Althouse. A few really good ones are just a bit too focused outside my area(s) of interest to keep my attention; Rick Hasen's Election Law Blog comes to mind as an example. Others I watch that might be of some interest to ELSers are Charles Franklin's Political Arithmetik (great for polls & survey research), Marginal Revolution, Andrew Gelman's blog, and the Social Science Statistics blog at Harvard (the latter recently had this nice post and discussion about differences between statisticians and "econometricians").
So, some questions: What do you read/write/comment on? What great ELS-related blog(s) have I missed? More important, how do you decide which ones to pay attention to?
