Curbed National: Inventory-R-Us

1) U.S.A.: The graph above represents national new housing inventory. Notes The Oil Drum, "The level of inventory is not high by historical standards, at least not yet, but the rate of acceleration in the last few months is really quite dramatic." [Calculated Risk via The Oil Drum]
2) Los Angeles: The Lower East Side has BLUE. Not to be outdone, West Hollywood will soon have... Cesar Pelli's Red. Oooooo. [Curbed LA]
3) San Francisco: Dataporn overload! Now that San Francisco has GarbageScout, can we get CabTracker ("averages the last four hours of cab routes into a map, then lays over that the routes of ten cabs in real time") here in NYC? [Curbed SF]
