I suppose this had to happen, the University of California at Berkeley is supposedly offering a graduate course in blogging. The course would be part of the school's college of journalism.
Is blogging a form of journalism, a form of self-satisfied egotistic key-tapping, or some mix? Judge for yourself and take a look at Sales Master World for one take on this and then at ktheory for a blogger's perspective.
While you're looking around, see if you can find any substantiation for the existence of the class at Berkeley.
The Sales Master World has some good reading including this: "To a large extent, bloggers are more interested in a point of view or the power of an idea than they are 'readers.' While the thought of a worldwide audience is certainly an ego rush, many bloggers would continue blogging for an audience of one. Think less about what I can do for you and more about what you can do for me."
