Teach Yourself Angular in 11 Minutes and 6 Seconds

I am often baffled by which articles and videos I publish that becomes popular. The video below for instance for weird reasons seems to be one of my most popular tutorial styles videos ever, which is surprising considering I'm proclaiming to be able to teach you Angular during its 11 minutes, and I barely touch upon Angular in fact. Even weirder is the fact that I've been trying my best to even hide the video, de-emphasising it, by making it "unlisted" now for months, since I personally consider it to be too low quality for wanting to publicly display it on my channel. Still, week after week, month after month, day after day, it seems to be amongst my top 3 most watched videos - So obviously people are sending it back and forth to each other somehow as if it was some sort of hidden secret, or the path to the holy grail or something.

What's the Lesson Learned?

I'm not sure to be honest with you, maybe that the best teachers and tutors are "obstacle removers"? Maybe it's not about how much you can teach per minute, but rather about how much obstacles you can remove? Or maybe it's the dark humour of me proclaiming to be able to do something everybody knows is impossible to do, yet still surprisingly (almost) capable of delivering? I don't know to be honest with you. Suggestions ...?

In fact, I had to rewatch it today to try to figure out why it's so popular, and I honestly have no idea. I guess we could say that the universe works in mysterious ways ... ;)
