Here's a 45 minute-long live recording of a master class session I did last week in New York. No slides, no script, just a riff.
(Here's a high bandwidth link to download the same file)
(and here's the transcript for those that would rather read it.)
Some people have recommended that I start selling these recordings in the iTunes store. For now, I think it's more interesting to share them for free, to encourage you to share them and to see if we can change anyone along the way. Feel free to post in other places to cut down on the bandwidth bottleneck.
