Really interesting look on Why critics of Rails have it all wrong, regarding how some of the Ruby on Rails community feels that Rails 3 was a huge step backwards.
The idea that Rails 3 was a major step backward was recently reiterated by both Giles Bowkett and Matt Aimonetti. Both of them painted building ActionController::Metal applications as some sort of byzantine, impossible task which can only be accomplished by a Rails core member. Are people actually building lightweight Rails applications using the newfound modularity of Rails 3?
I haven’t actually looked deeply into Rails over the last year or so, but it definitely feels less accessible lately. NoSQL databases, CoffeeScript, etc are fine, but the “feel” of the current Rails is far from that original Blog in 15 minutes screencast.
