You're right. I should have said "a todo app" or something similar - Rails was what came to mind first because of 37 Signals et al who make a lot of that kind of stuff.

Aside from that, I'm a huge fan of abstracting commonly made and agreed upon technical decisions further down the stack, making higher level development much simpler and less technically challenging - which is from my understanding what RoR was/is largely about. That's not to say that RoR as a framework isn't in and of itself a technical achievement though.
