Technorati ranks Env-Econ 13th (420 links from 124 sites) among blogs with "economics" tags: http://www.technorati.com/blogs/economics. Two spots behind Division of Labour (381 links from 131 sites) and ust in front of Economist's View (604 links from 119 sites). Note that adding env-econ contributor Mark Thoma's blogger links (17) would push Economist's View ahead of env-econ.
These are 3 of the 4 econ-blogs that I recognize in the top 20. Coyote Blog is in the top 10. My guess is that among Technorati users we're the only ones to bother adding "economics" tags to our Technorati profiles/accounts. And everyone else is using Google's blog search.
Also, a 30-day moving average should be insensitive to a dip in traffic on the weekends, right? Our 30-day moving average at Sitemeter dips every 7 days and we can't figure out why. I e-mailed Sitemeter with this question and the response was something like: the 30-day moving average is measured using a methodology that is so complex that we can not reveal it to Sitemeter users.
