As for "incompetent design" - I don't know what you are on about. I think that Rails 3 is a frigging triumph of elegant, modular design. There are very many gems in the ruby ecosystem that I believe any unbiased person would say demonstrate exemplary design. In fact, I would say that the average rubyist is much more concerned with good design than, say, your average java dev. The whole reason I switched to ruby was because of the beauty of the language. And what is beauty but good design applied?
Of course there are always exceptions but on the whole I think this comment is quite unfair.
