I don't agree that it lacks substance, the conclusion, and also the conclusion that I have made according to rails is that it's "good enough" for almost any web project. It's safe to have it as a default choice. There's a good community, fantastic libraries, constant innovation, and people are really happy developing with it.

The notion that there's nothing wrong in choosing rails -- is now acceptable mainstream. Even the hard ass Java developers at my work can acknowedge that yes, it speeds up development to use a field tested full-stack framework instead of rolling your own framework for every project. (Only recently did we come to a truce, and now I can refrain for a while to try to push even wackier frameworks on them like some Clojure based ones, because Rails is good enough for me )
