Did you know that Nicholas Kristof has a blog? As far as I can tell he’s the only NYT columnist with one (hosted on the NYT site, anyway). It’s a neat idea, though rather clunky and difficult to navigate in practice. The idea is that he can use this quasi-blog to interact with readers, but it mostly seems to involve just printing reader letters.
Regardless, go here and scroll down to the bottom two posts, which consist of letters on his execrable column on environmentalism. Most take him to task, justly. He does not respond.
