I would really like to read about that performance comparison. When something is written I can skim it to see if it’s worthwhile my time. With videos… i don’t even bother. My experience with videos is that most of the time a 5 min content is dragged on for way to much time. And you neither can skim a video, nor get back easily to a particular moment that’s interesting. When it comes to programming, videos are good for… wait they’re not good for anything 
Update. I just read it again, and want to clarify one thing. It’s not that I am attacking you. Or that I cant appreciate someones work, just because it’s video, it’s not like that at all. It’s just that I’d much rather read a chunk of text, than watch a video (unless it’s a TV show or smth 
). And I believe there are more people people like me and thats why I believe you would find at least few readers (if not many) for your blog if articles would be about interesting topics. 
Oh I always loved those ASCII casts 
I really makes you think, that the creator value reader/watcher time, which is very rare.
