Well it looks like your options have been narrowed down to: (in order of appearance)

• javascript
• Ruby
• Perl 6
• Python
• Java
• Assembler(?!?!), including RT11 and CP/M
• SQL
• PHP
• C
• Erlang
• Pure
• Haskell
• C#
• .Net
• C++

Now that _that's_ settled it looks like you have a clear choice ;-))

(As eyespoplikemosquito stated earlier in his post) You're going to have a tough time choosing via informal survey without having a clearer idea of what you want. Is this purely for education? Is it for for a project? Work, career? What languages do people know at work, school or local groups?

That will inform your decision more but you will still have to pick a few of theses languages (out of a hat if you have to) and take them for a spin over a few weekend.
