I've stopped clicking on YouTube videos that give me no idea what they are going to be in the thumbnail/title. For example on Linus Tech Tips second channel ShortCiruit a good chunk of their videos do this. Latest one from 3 years ago in my sub box "I almost hurt myself open this...." and the thumbnail is him maybe holding a big TV with a game on the screen. I can't tell if it's a big monitor, a tv, or if the video will be about what's on the screen in the thumbnail. I wish that videos/news/blogs that use titles like this could also just tack something on the end in brackets saying a couple words about what it's actually talking about.
Too often I'm having to fall prey to the clickbait just to see if maybe the video will interest me or not. More often than not it doesn't and I just wasted time.
