Hi Sadness I am not singling you out for criticism - lots of people do this thing, just posting a YT link, and which I find difficult and tiring.

It would be cleaner if you posted a summary, something like "Here's a video which explains...whatever it does explain... and details the connection between x and y"

Then I could decide if it was something I would be interested to watch. In this instance that guy's gimpy face doesn't make me want to click at all, but maybe that means I would be missing something important.
