For me, the biggest problem with rails is that it boots really slow on development so it's really boring.
I switched to padrino a while ago due to this issue. Also I prefer padrino's router since it's more explicit.
rails boots fast if you have few files but when the project is big it is a pain, it takes a lot of time to boot and it's not fun. That's why the article says rails is "a day job".
I just hope the rails team don't think like you.
