The use of Blend was a bad idea and took you completely off topic. You never actually showed the source you were trying to make in the video. You should have shown how it worked, not glossed over it in Blend.
Think of TouchStudio (TouchDevelop) as a modern version of the arrival of the Borland IDE, but for SmartPhones. Borland brought the ability to create programs to people who never considered it before.

Great start guys, now let's see it change they way we see our phones.
