The videos of the Lang.NET are online. Again wonderful geeky talks about programming-languages and other programming-related stuff: http://www.langnetsymposium.com/2009/talks.aspx
Additionally there are some back-stage talks on channel9. Gilad Branchas Newspeak is most interesting. The concept with no global scope, objects as services etc. is fascinating. However it’s currently only in a experimental, partly in a conceptual state. And event if it will become usable in like 5 years, I don’t see it adopted by the masses.
