"Erlang needs a killer framework." I don't agree with this. Erlang has already frameworks but that is not the selling point of this language and environment. For me the reason to use Erlang is the concurrency patterns and the tooling. RoR is great to get you off the ground but when you hit bigger scale you have to replace it with something that is more memory efficient and supports high number of concurrent connections. Several companies proved this including Twitter, Opscode etc. Erlang on the other hand lets you to use the same environment from day 1 to the time when you have 10M+ active users. You have to work on it but it is possible and there is no need to ditch the entire system because you got popular.
