I listen to most videos at 2x speed and most of them are still too slow. There is so much dead air and lack of real content. I have made some videos here on DTube. I posted one just yesterday -- my 8 Principles of Foraging, using Gingko nuts as an example.
I try to make my videos worth people's time - I edit out dead space and try to keep it focused. Keep it moving! I also put text in my post, not just the video. So folks can get something out of the post even without watching the video. I can read so much faster than watching a video. But a video is helpful for connecting with people and hard to beat for DIY content. I'm using video to push myself, too. I'm not so comfortable on camera and it's something I want to get better at.
