It shouldn't come as a big surprise that 800 people signed up for a free preview for a telephone course on how to make money from blogging. It's the next step, I guess, in the evolution of blogging as people go from doing it as a ego/branding/creative outlet exercise to something where they can make a few bucks. I think many people believe they can be like Darren Rowse, the fellow offering the course on tweaking Google AdSense who claims he makes more than $100K a year from blogging, but very, very few people are going to make a living from doing it. You have to give Rowse credit, however, for somehow convincing people to fork over $270 a pop for the course.
Mea culpa: This post has been edited to reflect the fact 800 people signed up for a free preview rather than the $270 course.
