If I can, I'll use the "advance ten seconds" button or tap the right arrow key to skip 5-30 seconds depending on the client, until I find what I'm interested in and scrub backwards until I find the natural start point.
I can count on one hand the number of tutorials or lectures that I've been genuinely enthralled by from start to finish.
I had one tutor that every time they said "oh sorry that's wrong, I've been coding in python today, not Java" I just used to log out and check out someone else's material on a video streaming site. Fuck you for pissing my time up the wall - if I wanted to do that for £1300 a year, I'd ask my local barman about his opinion on the taxation structure of the United Kingdom for those straddling tax brackets.
edit: and/or barperson - if they can pour a decent pint, they're all awesome to me.
