I had the same reaction, especially when I got to his paragraph about Sinatra (vs. Ruby on Rails). If Sinatra is more fun for him, more easy for him to understand, and more productive for him, why not use it to build things? It's possible to build very nice things on top of simple tools like Sinatra. To the author, I think you should give yourself a lot more credit.
