Although not an extremely poor tutorial, I'm not sure why you would publish it here for such a niche audience of people to appreciate it.
Now, I don't know if any of the info is wrong (probably not) but it definitely doesn't simplify anything, it more just throws terms at you. The hows and whys go almost unexplained, and there is no sound to compare anything to. I'm gonna be honest, after watching that I learned little to nothing.
I'd imagine this is probably a good brush up, but who'd be coming here for that?
PS: some of the flash animations took quite a few presses of the button and some skipped over the words instantly.
