I don't know who needs to hear this (well, actually I do, but no need to mention names), but links to YouTube videos no longer load a thumbnail or title here.
If you post a link that just says, "This is great," "Huge news," "Worth the listen," or "❤️ ," most people aren't going to click. Give us a little more to go on. We don't have time to open every link.
Yeah, I have noticed a lot of them are low-quality videos, like some unknown guy talking about a video of something that happened, rather than the primary source itself. Maybe he's worth listening to, but they've given me no reason to invest time finding out.
But sometimes it's people posting interesting things they want to be a little surprising, and they're not realizing that the particular choice of words they post to describe it isn't giving people a reason to click.
