The document discusses the social-web-pattern, which includes the follower principle of asymmetrical connections, activity streams and newsfeeds, the one-click gesture for sharing and redistribution, and connections to other web services. It provides examples of this pattern in use for mobile photo apps, news aggregators, Q&A sites, and in e-commerce through sites like Groupon and Etsy that allow following stores and sellers, and sharing purchases and favorites. The key aspects are enabling personalization, visibility, virality, and understanding user preferences through their one-click actions in streams.
