The document discusses the future of web services and social messaging applications like Pownce. It notes that Pownce started as a desktop application but later became a website, mobile site, and supported various third-party integrations through APIs. The key aspects that define an application are said to be the code, technology, infrastructure, features, rules, and limitations, not the interfaces. The future of applications is predicted to involve simple, hosted environments and cloud computing, moving away from traditional web pages. APIs will continue to be important for interoperability between applications.
