"For example slack is an incredibly successful product. But it seems like every week I encounter a new bug that makes it completely unusable for me, from taking seconds per character when typing to being completely unable to render messages. (Discord on the other hand has always been reliable and snappy despite, judging by my highly scientific googling, having 1/3rd as many employees. So it's not like chat apps are just intrinsically hard.) And yet slack's technical advice is popular and if I ran across it without having experienced the results myself it would probably seem compelling."
