I annoys me that people never seem to realize that 37Signals is a company that has "won the lottery", as David likes to say when pejoratively describing the success of companies that have chosen a different route, in a major way with Ruby on Rails. The popularity of Rails is a huge contributing factor to the success of 37Signals. And without Rails, nobody would ever have picked up any of their books. 37Signals is a popular counter-example because they promote themselves, and the vast majority of their ability to promote themselves through talks and books is direct result of hitting a grand slam with Rails.

I would guess a greater percentage of their customers have never heard of Rails.
