Ask HN: What are the most innovative web frameworks?

Meteor is kind of nuts: https://github.com/meteor/meteor, real time, database abstraction built right into the browser/js, no lag for saving as it uses background sync.

I wish I had a reason to use Meteor because it looks like a lot of fun!

very cool debugging nightmare,

if you like coding in text editor(vim, notepad etc.) and debugging with println`s, meteor is for you :)

http://zotonic.com/ is pretty innovative (the event-driven model e.g.) and so is http://www.helma.org/ (elegant, server-side JS, heavily used by large websites like orf.at for many years, but not widely known).

The Geddy framework for Node.js is doing some pretty cool things these days. It provides a good architecture for real time MVC apps.

Yammer is using it for it's file uploads service.

It's got a great website and it's docs aren't bad either.
