I just came across this link--I haven't done much reading yet, but the site promises to be a great place to get a better understanding the financial crisis. I plan on spending some time there this week.
I have listened to Alex Blumberg's "This American Life" show (called "The Giant Pool of Money"), and it helped my wife and me understand the root causes of this debacle, though it was released before the financial system became the debacle it is today. From what I understand, the sequel to the show will be on TAL today, and it will pick up where the last show left off.
