This is good on paper, bad in practice. One of the best ways to retain and understand information is to explain it to yourself. As in talking, having a conversation with yourself(I do this very frequently). It makes sense that to show you understand something at least on a beginner level, to create a blog/video/tutorial to teach others about what you just learned. As many others have stated though, this leads to a mass of useless tutorials being created and pushing down the actual good information about that topic in search engines. There are ways around it, disclaimers are a good start. I'd put in a very visible style, a note that says something like "I by no means am an expert in the field, I only just learned about this topic and am creating this tutorial to try an re-enforce my own knowledge. This information is not assured to be valid in any way and it should not be cited or used as such." Even after saying that, I'd still encourage this behavior on personal blogs. No one should be taking technical information from a personal blog without additional research on a topic anyways. Many people have blogs for themselves, not others. The action of some people stumbling upon a personal blog is just a coincidence/bonus. Back when I was first getting into infosec, I'd write personal tutorials on exploit techniques(cross-site scripting, SQLi, LFI, RFI, etc). I never posted them, because I didn't care for anyone to read them. They were just for me so that I could re-enforce what I already learned.
