Yes, that was a great read. What I mean is that the overhead of understanding and keeping the abstractions in your head (promise object, resolve/defer/reject, returned promises, chaining) almost nullifies the advantages it offers. I think promises are great in some circumstances, but unless they catch on as a standard way of working with async calls, they will remain just a 'clever' thing you can use, but most developers won't understand, and will make your code incompatible with everyone else's. It's a chicken and egg problem.
