erlang

I recently started looking into the erlang language. It is a functional language somewhat like lisp, but concurrency is built into the language in a very fundamental way. Has anyone out there worked with erlang before? Any opinions on the language?

Erlang is awesome. I don't think I'd really consider using any other language for applications requiring significant concurrency or network features.
I wonder, do people like this ever actually program? Or do they just sit around, download the toy languages du jour, write Hello Worlds in them and fantasize about how cool it's going to be when somebody is finally going to use them? (Not counting Ericsson.)
