This looks really cool, and I signed up for the list.
That said, I'm very curious how accessible the videos will be. Screencasts are cool, but since I'm deaf, they're not always ideal for me since many of them aren't captioned and I never know if what they're showing on-screen is accompanied with a voice over to the effect of "You may see it done this way, and it's terrible, please don't do this." :)
Looking forward to seeing more about this!
