Dunno - I think I got myself on the wrong side of the Great Firewall of China. According to Google Analytics I don't have any Chinese readership (although to be fair, I don't have much of a readership any which way you look at it). And my friend in Chengdu couldn't access this blog. My blog on learning Chinese does however, so it's not some kind of blanket Blogspot firewalling. Maybe my excerpts from a chapter of Collapse did the trick. Hey - if you're reading this from the PRC - let me know!
[Addendum: Paranoid. Severely Paranoid. I checked Google Analytics (properly this time) and I do have a Chinese readership after all. Chengdu and Shanghai both appeared on my map.]
