The day after I got the parking ticket I was able to pay a visit to Andrew Michael Baron, who with Amanda Congdon have created Rocketboom. This videoblog is the first to break into mainstream coverage (BusinessWeek and the local CBS affiliate) and they are working hard to define this new short form medium.
Someday the internet will be home to zillions of small channels. Rocketboom is showing that you can inform and entertain with production costs about that of a tank of gas.
