looking for related blogs/links

What are good other resources on the internet for social science, cognitive science, and artificial intelligence (or computation more generally)? I'm looking for blog-like things in particular -- stay updated on new research and the like.

here's the list so far, trying to be interdisciplinary as possible. A cognitive neuroscience or neuroeconomics blog would be a nice addition.

• Marginal Revolution (i really like this one, except for the annoying pro-ayn rand jokes. well they're just jokes. right...?)
  
• Daniel Drezner
• Language Log

other possibilities... need to search technorati.com for more...

• neurodudes
• http://www.kybernetica.com/
• http://www.karmachakra.com/aiknowledge/
  

Perhaps mailing lists and/or newsgroups are better for some of these topics.
