And like anyone who's ever tried to build a large front-end application with _just_ a library (jQuery) will tell you: it quickly gets way out of hand and completely unmanageable before the product even releases.

One the same note, if all you need is a quick animation when a button is clicked, and some extremely trivial dynamic elements on the page, a large framework like Sproutcore is going to just get in your way, and you'll spend more time trying to learn how the hell to use the damn thing and twist it into doing a task that's outside of its primary purpose.

In short: use the right tool for the job. The anti-framework posts to come out of the woodwork this morning on HN are pretty disheartening. I sincerely doubt anyone that's completely against using a framework has ever written a large application that they need to support, that didn't end up as a giant mess of spaghetti code stringing libraries together haphazardly.
