It is not. HN isn't a place that guarantees advertising or publicity. Readers and commenters will click on this thread thinking "is there a better way of writing markdown" or "I wonder if I should be using a different editor" which makes all editors relevant information. And honestly, if I see an advertisement _without_ any criticism, it sounds too good to be true to me. Seeing a comparison between these editors is going to provide a thousand times better information then just people talking about one or saying "hm, that looks interesting, I'll check it out sometime".
