Great article.
First time the housing market goes down since the 1930's huh... ?
Usually when a market goes up for a long and sustained period of time, it leads people to the wrong impression that the rules of the market somehow don't apply to this magical little market and that it never goes down [I've heard several professors state that land will always increase in value as time goes by].
In this such markets, once people wake up and see that prices in fact do go down, panic takes over and the crash is [for lack of a better word] spectacular.
