I think you should learn Brainf*ck. It has awesome mental/intellectual benefits to you as a Erlang lover. No, but really.... ! And if you don't you will suffer! Muahaha!
I think its kinda silly that people will just ignore a language because it doesn't look like java/C/pascal. Its not like the syntax of erlang is stupid, or pointlessly obtuse.
Doing Erlang at the day job for the last few months has been awesome. I really wish it would catch on more. Maybe when the JVM supports tail-call optimization and there is a JVM implementation of the runtime...
