This is the semimonthly open thread. Post about anything you want, ask random questions, whatever. Also:
1. Still busy. Continue to expect less blogging.
2. There were some good counterarguments to some of the links in my last link roundup that I wanted to highlight before anyone gets misled. Luis Coelho points out some problems with the microbiome-sweetener theory. Albatross doesn’t believe that hospitals are raking in the dough. And Scott Sumner says contra Paul Krugman that interstate migration to the south is driven by low taxes, not good weather.
4. I’ve given up on Ozy ever posting any more open threads at their place, but you still can’t discuss race and gender here. No, life isn’t fair.
