Video tutorials.
A well meaning individual takes a lot of time cutting/stitching together numerous takes to make something that's exactly what they would have wanted to see to do whatever the example is in the order they need to do it. Problem is I always need to do stage 7 before stage 4 so I get bored, then find myself clicking randomly on the timeline looking for the bit I ignored when it was covered as it's actually important later. Then I have to find where I was...
Are you really supposed to sit there for 20 minutes mindlessly copying someone doing something you don't want to do? It's like being back in school, except instead of an exam which can be blagged I actually need to learn something.
What's wrong with written tutorials with a couple of screenshots, where you have all the time in the world to experiment and can search the text for whatever when you get stuck? No money from YouTube, that's what.
