More on this later, but my vote for the "One Post You Must Read On Our Current Financial Crisis, If You Only Have Time To Read One" award goes to this post from Brad DeLong. What I like is that it provides a good summary of "how we got here" while doing so in a way that generally avoids the perfect hindsight-driven tendency to pronounce Greenspan, et al nothing more than a bunch of fools and knaves. If your explanation is based on everyone having been fools, you are likely to miss something big.
