I just discovered a very useful blog: the "Social Science Statistics Blog" from the Institute for Quantitative Social Science at Harvard. LOTS of excellent resources and interesting discussions here. This is their description of the blog:
"This blog makes public the hallway conversations about social science statistical methods and analysis from the Institute for Quantitative Social Science and related research groups. Expect to see posts on trends in methodological thought, questions and comments, paper and conference announcements, applied problems needing methodological solutions, and methodological techniques seeking applied problems. Also included are summaries of papers and comments from a popular weekly research workshop held here and billed as a tour of Harvard's statistical innovations and applications with weekly stops in different disciplines."
