I've actually always wanted to use Erlang and I've worked on quite a few projects where it probably would have been the best solution possible (massively concurrent websocket backends for example). The two things that made Erlang a non-starter on those projects were: 1) It's hard to find people that have production experience with Erlang 2) The perception is that batteries are not included (even in comparison with Go... if you have some information to refute that notion I would be more than happy to learn more)
