A "Top highlight" from an arbitrarily selected post on Medium. These top highlights can function as a crowdsourced "tl;dr" -- although not every post enables them. Highlights can also be discussed in comments following the post. Incidentally, here maybe the medium is the message -- one person's highlight becomes a possible occasion for further discussion. And yet, the way comments work on Medium, there is no such thing as a discussion thread! So there is only a collection of perspectives on the piece -- a sort of "functorial" utopia. (There are discussions on Medium, but they're just not very typical or obvious.)
