Not that I want to tamper with Greplaw's current poll, but the speech Bruce Sterling gave at the O'Reilly conference a couple of days ago may prove to be this year's best speech on open code. The speech can not be easily be summed up in a few sentences, but if you are interested in open code you should read the transcript. Science fiction writer Sterling spans over a wide range of subjects, like the nature of the Cathedral, the gurus and why open source, basically, is about hanging out with the cool guys.
