Andrew Gelman wrote Less Wrong's favorite textbook on advanced Bayesian statistics. His blog is here. Some good stuff like a recent post on why the hot hand actually exists which I still don't completely understand.
I wonder if anyone has made any effort to systematically catalogue academics who blog?
I want to check out more rationalist bloggers.
Please list no more than one per answer. That way I can see from the upvotes/downvotes which ones are the most popular (and hopefully which ones are most worth checking out).
I know that popularity isn't a perfect signal, but hopefully it is a better signal here than on the rest of the Internet.
