Why is Erlang so unpopular?
zdmc23: I think that more people don't commit to Erlang because they're afraid that it's just "the cool thing" - for now.  It seems like more and more people are becoming aware of the importance of learning at least one functional programming language, but perhaps aren't sure which to commit to.  I personally was a bit torn: Erlang has some great features and is production tested, Clojure is Lisp-esque (kill two birds with one stone) and has access to the Java libraries, OCaml is blazing fast, Haskell seems to be the pick for the "eggheads" and has lazy evaluation (purists seem to gloat over this one), etc...  I think it comes down to risk...
