I guess you have to define what "taken off" means. I'd agree that Erlang hasn't taken off in the way (say) jQuery has, but the use-cases and audiences are pretty different. There are many applications written in Erlang (ejabberd, RabbitMQ, CouchDB, SimpleDB) that are the fundamental component of larger apps - I'd say this is a "taking off" of sorts.
