Contrary to what the echo chamber may sometimes indicate, not everyone is solely a web programmer.
(cpp w/ boost here)
I feel like you problem is that for most of the languages you listed, there is more than just one common framework in use. For example, if I am a Ruby dev using Sinatra or a Python dev working in Twisted, I'd probably be a pretty mainstream software engineer, but I'd fall under "other" on your poll on both accounts.
Yep, and I think that's OK, I'd say Ruby/Sinatra is a more rare combination.
This weekend, my Python web hacking started out using Aspen and is now using Flask. I've used Django for one of my projects in the past.
Well, I've been using OPA for quite some time and it rocks.
Caveat: I'm a member of the OPA team. But it still rocks.
At work I have to use Java, but in my spark time I use Haskell and Yesod.
Clojure mostly. Hands down my favorite language to do random hacking in.
