I'll admit it, I've been subscribing to a couple blogs for a while now. They're boring econ/politics blogs, but I think they're interesting. They are : The Marginal Revolution, a very popular economist blog by Tyler Cowen and Alex Tabarrok, Environmental Econ, by Tim Haab and John Whitehead, and the blog by Greg Mankiw, a Harvard professor and ex-Bush econ aide. I can't imagine many finding these interesting, except maybe Marginal Revolution. But I've just added footytube to my list. It's a soccer video blog so it again my not be something anyone is interested in.
Shameless plug-
