I like the rational, smart tone of discussion on HN. What other websites do you go to for these kinds of discussions, particularly on non-hacker topics? Like most people here I'm interested in various areas -- technology, economics, politics, psychology, and mathematical modeling of all kinds -- and enjoy discussing them with other analytically/quantitatively minded people.
Some blogs, such as Freakonomics, Marginal Revolution, and Overcoming Bias have interesting commenters. Metafilter is full of smart people, but is a bit too heavy on the arts & humanities for my taste. Apart from HN, where do you get your fix for smart discussion?
Both are incredibly smart blogs, with very smart commenters. Their main shtick is bringing historical perspective to contemporary problems of government and economics. The result is fascinating and eye opening. I've learned more history from these two blogs then I learned from majoring in history at Yale.
