A lot of sites with YouTube embedding have rules about posting videos where you have to comment about the video and why people should watch. I don’t click any of the videos on hexbear or lemmy because I’m not going to sit down for 20 minutes to watch something by someone I don’t know.
I don’t think people need to write more than a sentence or two and I wouldn’t expect there to be anything on stuff like music or 10 second comedy sketches. But holy hell could we use something for video essays and political commentary.
