Seeing the 1:42:51 length scared me at first. That's going to take me days to get through given how much free time I have per day! Anyway best bit is to skim through bits of it. It is all interesting and good but I do prefer it when he talks about code.
This is where I find 1) downloading the video and 2) playing it back using a local media player to be vastly superior to viewing online. I can squeeze the window down to a small size (400px presently), speed it up (150%), start and stop it at will, zoom to full screen, and _not_ have to figure out where in a stack of browser windows and tabs it is.
Pretty much the point I was making some time back where I got in a tiff with a documentary creator for D/L'ing his video from Vimeo (its browser player has pants UI/UX in terms of scanning back and forth -- the site switches videos rather than advances/retreats through the actual video you're watching).
And then as now I maintain: users control presentation, once you've released your work you're letting your baby fly. Insisting that people use it only how you see fit is infantile itself, and ultimately futile.
P.S. In Chrome I can play almost all Youtube videos at 2x speed. Most presentations are still very understandable. I've been doing this for a while, maybe start at 1.5x.
Anyways, just a tip. Its saved me hours and keeps slow speakers from getting boring.
