I'm sure I'm not alone - after decades - already knowing far too much about C, so that any article I'm likely to read either I'm like "No, that's wrong and I even understand why you thought that, but it's still wrong" or I just nod along and sigh.

I spent a substantial fraction of my professional career writing C, and I remain interested in WG14 (the language committee) and in several projects written in C though I avoid writing any more of it myself.

The reason it's so widespread is called "Worse is Better" and I believe that has somewhat run its course. If you weren't aware of "Worse is better" a quick Google should find you the original essay on that topic years back.

In contrast when I read an article about say Zig, or Swift, I am more likely to learn something new.

But I can certainly endorse your choice to write about whatever you want - life is too short to try to get a high score somehow.
