A couple of other excellent bits of content from the O'Reilly site:

• "Buy Where You Shop" by Tim O'Reilly wherein O'Reilly makes a very sensible suggestion -- if you like to hang out at bookstores and look at the books, you should buy there rather than saving a few bucks online. Everything he says is applicable to the music biz as well.
  
• "Information Architecture Meets Usability," an interview with IA guru Lou Rosenfeld and usability guru Steve Krug. A fun, wide-ranging discussion, useful at least for the answer to the burning question, "Hey, aren't information architecture and usability the same thing?"
