Best Post of 2010?

We’ve been light on blogging with the holidays this week.  So, as 2010 comes to a close, I thought I’d open a comment thread for those readers still trolling the blogosphere this week to note your favorite Opinio Juris post of the year.  For me, it turns out I’m fond of bird dung, at least when it becomes grounds for exploring the origins of territorial sovereignty.  Other nominations welcome.  And Happy New Year.
