As I point out here https://news.ycombinator.com/item?id=7437872 I think Steve Klabnik's argument is actually conflating two phenomenona. One that there are a set of tools/gems that are more conducive to productivity than the Rails defaults (HAML/Postgres/Rspec) and another that some developers find the Rails architecture to be a pain point.

They are overlapping camps but not exactly the same.
