2010 in review

The artificial intelligence engine at WordPress (who hosts this page) sent me an email with some stats on how the site has been doing since I set it up back in June.

His resulting post on The emergence of international order: The case of MFN treaties in the 1860’s is worth a read! Also, David’s post sparked a nice follow up blog… Continue reading An animation
