The article's title is a misnomer. (I can't tell whether that is intentional on the author's part or not.) The article describes making something you, the maker want, because you find it interesting--but then says that other people will end up wanting it too, because they also find it interesting. So you're not making something nobody wants: you want it, and you're not nobody, and others end up wanting it as well.
What the article really seems to be advising against is making something, not because you want it, but because you think others will want it. The article is basically arguing that that doesn't work. But why doesn't it work? Because in fact doing that ends up making something that nobody wants! You don't want it, and once you've made it, you find out others don't want it either.
