Here come Elixir and so far it have decent momentum. It got mix, ecto, etc.. tools. And all of a sudden the creator started to contribute to Phoenix framework. It got 2 books now and an OTP books coming out.
In general, I think Elixir is executing pretty well. If pheonix hit 1.0 that is comparable to RoR and can make restful service dead simple with oAuth, elixir might have a chance.
edit:
From what I've gathered:
The blog posts and online community of Erlang is mostly technical. The community at the local meetup is very against new ideas, they're stuck in a cycle of continuing the same path while complaining about how to get adoption rate up for Erlang...
