Hi DHH,
Huge fan of your work. Been in love with Rails since the pre 1.0 days. Our team internally (we have an existing Rails 3 app that we want to improve rendering performance) has been going back and forth with "Rails should emit JSON and render client side" and "We should be smarter about caching and AJAX-ifying our pages".
Your post has given more ammunition to the Rails-only side, so that is really awesome; thanks for that!
There are reasonable arguments on both sides.
For Rails Improvement:
* We know Rails
* Scaling Rails is a solved problem
* You can "just throw money at it"
For JS UI:
* We know Javascript (http://www.github.com/toura/mulberry)
* Why spend server $$ on boring HTML rendering?
* We have better GUI test tools in the framework side (we can unit test our componentized JS GUI much easier than a mashed-together Rails ERB
Read the rest
HTML)
* We don't have that much money to throw at it, and that's wasteful besides
Presupposing, of course, that the server rendering JSON takes less time than stitching together ERB and the developer toolkit isn't any harder, would you find it more interesting?
Thanks,
