I’m not forcing to invite my audience here. I’m trying to keep it focused on my interests. I feel that I don’t have to worry about boring 90 percent of the audience—because [the audience for my blog] self-selected themselves as wanting to read this, I can be much more authentic and much more liberated to talk about what I really want to talk about, rather than trying to anticipate the needs of a scattered, diverse audience like a magazine has.The book is also self-selecting. If you’re not interested in the concepts in the book, don’t buy it. If you are, I’m going to go deep, and that’s great. But books—and blogs—are focused, whereas magazines are not.
