While interesting, I'm not sure how that will translate into practice. How easy is it to hire up an organization of Erlang developers, versus, Java developers?

While interesting, I'm not sure how that will translate into practice. How easy is it to hire up an organization of Erlang developers, versus, Java developers? I suspect Java's features as compared to Erlang will be good enough, that the specific use-cases enabled by knowledgeable Erlang developers will be non-competitive in the general developer labor market, but I am open to being wrong/educated.
