While I agree with your sentiment I think your analogy is a bit off... there is a big difference between adding a utility library like jQuery to your project vs. committing to the project layout of a framework like Rails. jQuery is actually less intrusive and therefore more of a no-brainer for me! (I know i use Spring as an analogy in my own comment on this thread, but despite being a framework you can use a lot of its libs without committing to any of its other aspects) sorry for being nitpicky i am just into analogies :)
