I just uploaded a set of new screencasts. I've been sitting on this since for 5 months now, just to show you how far behind I am in things. But I worked really hard to improve the production and post-production quality over my last set of videos.
Now that YouTube has an HD option, using them as the primary server is no longer a problem for me.
Head over to my Screencasts section for more details.
