Has anyone heard about the new programming language called F# ?

I hadn't. So (for me) NO.

Does anyone care about the new programming language called F# ?

I cared enough to look at the article but I'm not interested in .net so YES NO.

Has anyone ever played anything in the key of F# ?

YES (well tried to)

No? No?, and probably No? again? That's what I thought.
