There are entire channels devoted to making YouTube videos that show you how to solve a very specific error message for a certain combination of Framework X and Library Y.
This content is obviously great for SEO but the people making it often record it 30 seconds after finding the solution themselves and because it's video it can't be maintained, it just rots.
Often I'll get to work in the morning and see 5 new GitHub issues where people are making the same hyper-specific mistake. Why? They are all misled by the same new blog post or video.
That said, I love how passionate developers are about teaching each other. No other industry shares knowledge as rapidly, excitedly, and broadly as we do. Even if there's a lot of bullshit, I find the whole scene very energizing.
