Went back and watched two of the Little Languages 2 Workshop presentations. Specifically Joe Armstrong and Todd Proebsting's presentations on "Concurrency Orientated Programming", and "Disruptive Programming Language Technologies" respectively. I highly recommend both these talks to anyone who is the slightest bit interested in programming languages, or has any serious involvement in development. It is just unfortunate that they are only available as real-video. Still if you have r-v installed, they are both well worth the time.
