Two and a half decades later, as the little yellow notes celebrate their silver anniversary, it‘seasy to forget what a recent innovation they are. Thanks to their material simplicity, they seem more closely related to workplace antiquities like the stapler and the hole-punch than integrated chips. Instead, they?re an exemplary product of their time. Foreshadowing the web, they offered an easy way to link one piece of information to another in a precisely contextual way. Foreshadowing email, they made informal, asynchronous communication with your co-workers a major part of modern office life. —Greg Beato
