Web 2.0 Developing Web 2.0 Apps Challenging programming model Asychronous communication Ad hoc protocols Structured storage of unstructured data Limitless scalability requirements Little or no componentization Lengthy development cycles Quality control issues

Web2.0 Meme Map Strategic Positioning The web is platform User Positioning You control your own data Core competence

Core competence Services, not packaged software Architecture of Participation Cost-effective scalability Remixable data source and data transformations Software above the level of a single device Harnessing collective intelligence Tagging, not taxonomy : Flickr, del.icio.us Rich User Experiences : Gmail,Google maps, AJAX User as contributor : PageRank,eBay reputation, Amazon review
