That site promotes geeks as users of information. Playing games, using programs, ripping CD, etc. There are a few things about building hardware based on components, but little in the way of creating or doing research.

I didn't finish it as it was full of dreck, but I saw nothing about programming, soldering or wireboarding, working with sensors. The only think I saw about art or design was 'shooping or putting an image into a game. Why learn 20 some odd digits of pi when you could toss in some CPU to Great Internet Mersenne Prime Search or other distributed computing projects? Or spend time with the Wikipedia MySQL dump, load it into your own SQL instance, and geek out learning databases?

And so on.
