I've been wrestling with "what to learn next" recently and had kind of narrowed it down to learning Javascript (probably using Rhino) more fully and trying Erlang as my first functional language. I think this nudged me towards Javascript. Even if I stick with Ruby for most of my server-side work down the road--I don't deal with data center integration--it can't make me worse at client side stuff.
