What surprises me is that lack of backlash for the shoddy upgrade process... Moving from Rails 2 to Rails 3 is a nightmare, a documented nightmare in 3 parts http://goo.gl/2Xw7n http://goo.gl/2Xw7n Sure you can get part of the way by porting to bundler and upgrading to ruby 1.9.2, but there is no plugin or way to have an app work with both Rails 2 and Rails 3 at the same time. And this is a year after it was released with 3.1 just around the corner. For the upgrade you need to change boot.rb, application.rb your routes and all your other configuration. Potentially you may need to update a ton of views to allow for the xss protection. By themselves none of the changes in Rails 3 are bad, its just that somehow they managed to make it very very hard to upgrade, so less people use it, and it gets less testing and stuff regresses. I think if the team focused on a bridge / integrated upgrade path for rails 2 that allows you to switch to rails 3 seamlessly it would do wonders for adoption.
