Grandiosity aside, what's pioneering about Ember.js? AngularJS, Backbone, Meteor and even Dojo and YUI I think all have better claims to being pioneers. As much as people hate Rails and the Rails community for having this attitude, at least Rails had that wow factor when it came out and there wasn't really anything like it out there. Ember.js? What does Ember.js have right now that AngularJS or Knockout or Backbone or whatever didn't have a year ago? AngularJS is both easier to get started with, offers much more flexibility and is much more interesting from a technical standpoint, not to mention that its feature set is much deeper.<p>This is like Apple's marketing, except without the product and aimed at developers.
