IMHO we are trained to look for a home link in the header.
I'd say that, even though the author put a link in the article, it's easy to miss it if you read the whole article first, then try to find more informations about Kakoune :/
May be you're looking at a wrong place? It's just a simple <a> tag, it should work. I can see link at first word in the sentence "Kakoune is a (fairly) young modal code editor that has matured for as long and as well as a good red wine."
Probably not what's happening here. But even "simple a tags" regularly break on iOS, because Safari has heuristics to see if the hover effect is to show something (like a menu), so then the first click triggers the hover, and the next click the actual click. Really frustrating as the heuristic is often way off.
Do you mean something else?
