Simon has been developing websites since age 11 and running his own start-up company since age 16. He discusses the evolution of the web from a read-only static environment to one that encourages user interaction, user-generated content, and content sharing. Key developments include the rise of blogging in 1999, Wikipedia in 2001, MySpace in 2003, and Facebook in 2004. The term "Web 2.0" refers to encouraging users to not only read content but add to discussions by submitting their own content. Content and identity aggregation make content easier for users to find and access, while distribution allows users to share updates across multiple social networks. The future may see greater identity and content management from a single online identity.
