Over time it seems to be selling more and more. The first month was pretty slow in sales though.
I've been doing more with Ember recently, and while some things are not as easy, some other important things are much easier. On top of that the views are easy to read. So at least for now I feel like Ember is better for me.
Rails isn't the answer to every programming problem, but I don't think that Rails has any more of a scalability issue than any other framework.
If you avoid doing things that absolutely won't scale you will be fine. Rails has no issues scaling, for 99.9% of the use cases. Regardless of the framework you use you will still have plenty of scaling issues if you have Twitter/Facebook level of success. But again that is a great problem to have.
