With my due respect to guys behind Ember, I don't understand why Ember gets so much attention. It has been in works for 4~5 years now but has not reached its 1.0 status. I've seen many complaints about its learning curve, documentation etc. However, when people talk about Javascript web frameworks to learn, it is often brought up as a candidate. Maybe someone can tell me why people think it will be a serious contender in this fast moving area.
