Ajax SPAs (early)

Partial page updates without full reloads. Became the mental model for every modern front-end framework.

Ajax mutated the web from document navigation to application state — then frameworks industrialized the pattern. The fad layer was calling every page an app. The durable win was asynchronous partial updates, now table stakes.

Case studies

Digg v4 rewrites the product and the audience — Traffic collapse and sale; rewrite consumed a year of product oxygen
Silverlight and Flash enterprise lock-in cliff — Multi-year rewrites of line-of-business UIs; mobile miss cost market share

Context

The browser ate the desktop

This decade invented the modern product cadence — and the habit of treating every new framework as destiny.
