John Baez This Week's Finds in Mathematical Physics has its 300th and last entry. He is moving to wordpress and Azimuth. He states he wants to concentrate on futures, and has upcoming interviews with:

Tim Palmer on climate modeling and predictability, Thomas Fischbacher on sustainability and permaculture, and Eliezer Yudkowsky on artificial intelligence and the art of rationality. A Google search returns no matches for Fischbacher + site:lesswrong.com and no hits for Palmer +.

That link to Fischbacher that Baez gives has a presentation on cognitive distortions and public policy which I found quite good.
