Community wise, if you give a 5 to Backbone and 4 each to Angular and Ember - I would be somewhat ok with that.. But still a 3 to CanJS is a bit far-fetched...

Community wise, if you give a 5 to Backbone and 4 each to Angular and Ember - I would be somewhat ok with that.. But still a 3 to CanJS is a bit far-fetched... CanJS github has ~500+ stars. 25 questions on SO. In comparison Github stars: Backbone - 13k+ Angular - 8.5k+ Ember - 6.5k+ StackOverflow questions : Backbone - 8.3k Angular - 4.4k Ember - 3.4k Based on this atleast I would give a rating of 5 - BB , 4 - NG , 3 - Ember and 1 or 0 to Canjs under community section. If you add Google Groups stats to this , then Angular wins out in community.
