Doesn't the old-fashioned Lynda.com offer much better videos? At first blush, Codeschool doesn't seem to be teaching so much as introducing. The JavaScript lessons seem way too high-level, and way too focused on frameworks and libraries (these are important, but only once you have the basics down).

I hope there's a kickstarter project to make some badges for challenges passed. People will then be able to sew them on their shirt, to show how good a programmer they are.
