Personally, I liked going to the NAB and RAB radio conventions. I learned a lot from the seminars and information, and a lot about the business, both good and bad. However, this guy makes some really good points, especially about the state of the industry: ["NAB: It's Your Party"]. I found this link quite by accident. It happened to be in the body of a Google email news alert about John Cox, which is weird if you think about it.
