I've been going on and on about Scala and lift these past few months to pretty much anybody who would listen. Lift, an alpha web framework for the object-functional language Scala, takes advantage of Scala's numerous features to provide a surprisingly powerful web framework in less than 10k lines of code. Take a look at the lift site to get an idea of what it can do. (Hint: David wrote a wiki in 45 lines of code)

I can see it doing for Scala was Rails did for Ruby.

So when David asked me if I wanted to be a committer, I jumped at the opportunity. I have a couple of patches going in my local SVN working copy mostly related to proper serving of MIME types and caching that I hope to get in soon.
