This has not been my experience at all. The more I publish, the more interaction I get. The more interaction, the more people keep reading (i.e., subscribe).

But this is clearly the author's experience, and if I were him I'd be deathly curious to determine the optimum number of blog posts per period for maximum interaction. One per year?
