I'm strictly a Python guy myself. If it were me, I'd try to reach out to various programming communities and see what the demand is for different languages. Personally, I will never have a use for anything that requires me to use Ruby, but I'm just one guy; maybe the Ruby/Rails communities have the biggest desire for this type of service. I am switching over to GitHub, though ;)
