Functional Programming (why not, everyone else has)

Functional Programming, what is it and why do I care? It seems like only yesterday when I didn't know anything about this and I was oh so happy. Ever since some crazy EMU student brought up Haskell, I've been lost in a sea of ideas and languages.

So far the very best resource that I've found for someone like me is "Functional Programming for the rest of us" at http://www.defmacro.org/ramblings/fp.html.

This article explores functional programming from it's roots, giving a foundation to so many of us who feel like we woke up yesterday and all of sudden everyone's talking functional programming.

Another nice introduction is on wikipedia: http://en.wikipedia.org/wiki/Functional_programming
