Key Trends in Globalization looks like a good weblog. It has a very nice post comparing te current stock price decline to 1929-33 in the US and the 90s decline in Japan. During the Depression, the Dow dropped about 90%. The Nikkei has dropped about 80%. Both declines took place over a long period of time.
