Welcome to the ninth issue of De Programmatica Ipsum, dedicated to the subject of Books, Blogs, Podcasts and Conferences. In this edition without a guest writer, Graham exhorts for a change in the way knowledge is shared in the industry, while Adrian argues that we have been manipulated by evangelization.

Knowledge-sharing activities in the software industry have a financial model that follows a long-tail distribution. Almost every software podcast you listen to costs its presenters money in bandwidth fees. A few of them make revenue from advertising. Most of the software podcasts that exist, though, are the ones you _don't_ listen to, and probably haven't even heard of.

One of the first, and still one of the most well-known evangelists in the history of technology, is without any doubt Guy Kawasaki. In an article in the Harvard Business Review he explained his role and gave an interesting overview of what it is, its consequences and benefits. Written, of course, for the audience of HBR, which might not have much overlap with the audience of this humble publication you are reading right now.
