As always, art_in_fl is full of surprises.

I'll abstain from arguing the merits of video vs. text as an instructional medium, but i really enjoyed the juxtaposition of the 'get off my lawn' take on youtube et al. ( not meant as an insult, please take this in the gentlest way possible ) and the reference to xkcd.com; which is a favorite of the the uber-geek/slashdot crowd.
