A Definition?

The term Web 2.0 is associated with web applications that facilitate interactive systemic biases, interoperability, user-centered design and developing the World Wide Web.

A Web 2.0 site allows users to interact and collaborate with each other in a social media dialogue as consumers of user-generated content in a virtual community, in contrast to websites where users (prosumers) are limited to the active viewing of content that they created and controlled.

Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, hosted services, web applications, mashups and folksonomies.

"[This is] not my mom's Internet…It's changing, and it's changing because we're looking at the share-shifting—the time people are looking at TV, reading a magazine, listening to the radio—they're not replacing each other; they're coming together." - AOL Exec / May 2005
