Even a sentence or two would help me judge if it’s worth my time. If I’m in public and don’t have headphones I’m not watching a video, especially if I have no idea what it is. If you tell me why I should care about the video I might make a note to watch it when I get home.

Secondly, I’m not just going to click a random link. I have no idea if it’s even relevant or a bot or a troll who just puts the links in every thread they come across.

which would be time intensive

The 5 minutes it would take them to type a quick summary is much less time intensive than the hour it would take everyone who sees the post to watch the videos and see if they care.
