I can't find the link right on hand, but I believe it was on HN - but there is a guy who does Ruby courses if memory serves. When I looked, he had around 9k followers on Twitter, and his courses have made over 1,000,000 to date. If someone is reading this is and it past of the Ruby community, they may know who Im talking to. While no books related but apps, I know 3 or 4 Indies who are a wonderful living (close to 1mil) with their apps and their social following isn't huge - but they are great of marketing outside of it. Not the same thing, but kinda the same thing.
