Business Opportunities Weblog has an interesting calculation of how much a blog is worth based on Technorati data and approximations from the recent AOL/Weblogs Inc. deal (just enter your blog’s URL and their script will generate an estimated value). It’s all just guesswork, of course, based on analysis by Tristan Louis, but as they note at least now there’ some starting point to estimate value.

My blog is worth $2,258.16.
How much is your blog worth?
