I'd wish people made normal tutorials (text + screenshots) instead of video ones. It's difficult to make a good one (that won't distract because of noise / recording quality / speaker without annoying voice), and at the same time you sacrifice low-bandwidth users and lots of time for the high-bandwidth ones - the important feature of a written document is that one can skim it, skipping the parts one doesn't need, focusing only on parts one doesn't know, while being able to see the entire context for the whole time.
I ran through these and it got me up to speed very quickly.
