This is a blade discussion forum. I'll never be considered what one would call the sharpest knife in the drawer, but I earnestly believe that generally means dialog and not drive by posting a random video with absolutely nothing added to the original post. Then again, maybe I'm out if line. My wife would most likely agree with that.
However are we going to talk about the video, or why it was posted, or why the OP finds it interesting, or what the OP learned, or what? It's 2021 and most everyone who wants to watch a video about any topic has a YouTube widget on their smarty-pants phone. What I, personally, find interesting is how posted videos made the person who posted them feel or what they learned. Hell, even it is nothing more than pointing out the guy spraying the blades is named Carl and goes to your church and cheats at bingo. At least that is something to talk about.
