Ross Mayfield's Weblog: Parking Lot Indicatr: "My uncle was a guru on wall street when I asked him where I should invest my paper route money. He said to visit the parking lots of Silicon Valley companies during the weekend. If the parking lot was full, there was a good chance they were close to a breakthrough or release.
But with enough mobloggers, a panopticon of performance may be a great leading indicator. So this weekend I started the Parking Lot Indicatr group and people have taken interest."
