I give up on watching youtube clips on this subject. I don't have any sound and most of them involve a 7 minute video of someone talking and waving a knife and talking and talking and talking and waving a knife about, lips still moving and then ........ 20 seconds of demonstrating whatever it was they were going to do.
That's the big issue I have with them. Too much waffle.
I must admit I've made some boring youtube vids though, just to show a little bit of knifemaking. Not massive long things so I don't feel too bad and they're easier than writing a description out in a way that could be followed. I don't think they get searched for and found though.
Unboxing videos should be banned.
