I'll have to disagree with you, I think that's a useful answer :)

It's good to hear these things even if it's just anecdotal and unquantifiable. I've only really worked with Ember and I feel the way you do. It's always interesting information from someone with experience in multiple frameworks (especially when they're all so young and we're all a bit lost as to which one to build our next project on).

Nice webapp by the way!
