This is one of my perennial bafflements, but the lack of suggestions on my request for political science blogs reminds me how odd the robust representation of economists in the blogosphere really is. Between Tyler Cowen, Mark Thoma, Brad DeLong, Max Sawicky, Dani Rodrick, Greg Mankiw, Kash Monsori, the folks at Angry Bear, and all the other econobloggers out there, a fairly broad channel has arisen for publicizing and popularizing relevant economic research in the political sphere. Not so with relevant political science research, even as it it would seem, if anything, more relevant. Why have economists taken to the blogosphere in so much greater numbers, and with so much more apparent success, than practitioners of other disciplines that also intersect with contemporary politics?
