Sure, that might happen. Or someone could spend their time writing code for their own projects instead of building a video for someone else's, because hey, he couldn't be assed to make his project interesting enough to spend time playing with. My first reaction, too, was "that's a pretty half-assed job," and closed the window. That makes it very unlikely that I go back and use it if I find a case where it might be valuable (because I won't remember it, except for the low-quality video and the lack of a demo - doesn't GitHub have a "pages" feature, anyway, where he could embed a real video on YouTube or something?). And if I'm not using it, there's zero chance of me going "hey, this could be great if X," writing X, and contributing it back.

It might be anathema to the "code is everything!" mindset, but part of getting people interested in your projects is presentation. You might think that's not the spirit of Github, but it's the way lots of (most?) people roll.
