Medium

Medium's contribution was treating the reading view as the product. Articles open in a single centered column with generous line height, a large serif face, and almost no chrome, which set a template much of the web copied. The signature interaction is highlighting: select a passage and a small toolbar lets you respond, share, or privately note it, threading reader reactions into the text rather than burying them at the bottom. A thin progress bar tracks how far you've read. The editor mirrors the reader, so writing looks like the published result as you type. Where it frays is the home feed and the membership wall: the personalized stream feels generic, and the metered paywall interrupts mid-article, clashing with the calm, frictionless reading the typography otherwise promises.
