The document discusses the rise of the "inverted web", where applications are built using client-side frameworks instead of server-side frameworks. It outlines the key drivers being HTML5 adoption, mobile usage, and improved JavaScript ecosystems. Several popular client-side frameworks are mentioned, including Backbone, Angular, Ember, React, and Vue. While the inverted web approach has clear benefits like faster development and improved UX, it also carries risks due to the radical change it requires in architecture and development processes.
