Im not sure I would call Erlang obscure any more, it has stories that end up on the front page often, with plenty of comments, is being used at a fair number of companies now. Sure it is not as well known as languages like Java, C, and Python, but there is only a dozen or languages at that point. Personally (and this is certainly not an absolute way to call this), I would say a language like Erlang and Haskell are fringe languages, where as languages like IO and Self are obscure.
