Dense, tactile, honest interfaces are having a nostalgia moment
A brief history of the Bloomberg terminal drew praise for terse, information-dense displays that show everything a person needs and nothing more. Someone compared it to avionics. "Before pixels: Modular industrial dashboards" got comments about the lost physicality of switches and the satisfying thunk of old controls. 56k.rip recreates the 1996 dial-up experience, and people joked that pages load too fast. The old thread thanking HN for not redesigning it, and the Reddit-app-nagging thread, add the contrast: the modern web is sold as engagement and tracking, not usability.
The pattern: people are describing a design philosophy where the interface serves a skilled user and doesn't perform for a feed. That is the opposite of LinkedIn and the push-notification app.
So what?
For professional and expert-user software, density and speed are product features, not a lack of polish. Bloomberg's longevity is the proof. If your users do this job eight hours a day, design for the expert instead of for the demo.
