This highlights one huge problem with video blogging - you can't scan through it quickly to see if it's worthwhile spending the time watching. This is a 20 minute video that probably has very few repeatable actions that someone else could use. The fact this guy ended up at Google means either he's exceptional or very lucky.
Not that it solves your problem, but it's useful to know the shortcut for speeding the video up and down: shift + , or . and use it in conjunction with the left and right arrows or j and l keys. It's the best you can do to skim clips.
