New web resource for learning and studying F#

Microsoft's F# language is a good choice for number crunching, but it's also a great language to learn functional programming. I just learned about a new web site from Microsoft Research devoted to learning and teaching the F# language called www.tryfsharp.org.

The site contains learning material including tutorials and demos, but also an online testing environment. If you are interested in learning F#, this is a good site to get started!
