cool for cats

Well, seeing as we're all enjoying the fabulous new Haloscan comments feature so much (!), how about a quick survey? Answer as many - or as few - of the following as you like and feel free to add any other thoughts ...

• Which language(s) do you think have a 'cool' factor?
• Why?
• Does new and exciting = cool in some way?
• If you had to create a new language, what features would you give it to ensure its 'coolness'?
• Do you think language learning / learners are 'cool'?
