What is “Web 2.0”?
• “Parsumer”: “harnessing the collective intelligence”– Databases and Metcalf’s Law– Blogging– P2P
• Rich user experiences– AJAX
• Loosely coupled systems– Reuse and reassembly
• Mashups– Continuous software releases (An ASP model)
• Real-time monitoring of user behaviour– Many devices involved– Simple programming models
• RSS versus SOAP and Web service discovery (UDDI)
