I have posted a question a while ago in Quora.com which says :
What do the creators of Emberjs think about Meteor?
The question never answered, I hope someone from the Ember core team answer it here or there.
I am only asking you because I trust you and I like what you did in Ember.
If I remember correctly there were a few opinions about various frameworks brought up in the 2 panel discussions at Throne of JS last year. Tom & Yehuda were on the panels & I think they talked about meteor a bit.
You may want to check the videos out, they’re worth a watch even if you don’t get your answer…
