According to the Business Opportunities blog, my blog is worth $13,548.96. That's certainly higher that I would have expected.
By contrast, the IE blog is worth $1,018,994.70. Honestly, that's less than I would have figured given that it's the #1 blog on MSDN and a CNET top 100 blog (Yes, I know this doesn't render correctly in IE7 -- we're working on it. Yes, I understand the irony.)
Anyway, fun stuff. How much is your blog worth?
