Agreed, which is why I meant some of them. Most of them look reasonably easy to follow, including the last step. I think in general, the owl meme has its purpose though: I'd see it as a reminder to be aware of "expert blindness": If you have lots of practice in a subject, part of your skills or knowledge will become subconscious and you're at risk forgetting they are acquired skills/knowledge at all. If you try to write an "introduction for beginners" piece without being self-aware about this, things can get frustrating for the people you're trying to teach. I guess the meme is the art equivalent of "a monad is just a monoid in the category of endofunctors"... :)
