What Is Web 2.0?

In the early days of the Web, individuals or organizations posted information, and users read it. These days, the line between creator and user doesn’t necessarily exist anymore. That shift toward more collaborative use is called “Web 2.0.”

Coined in 2004, the term refers to the greater participation, creativity, and information-sharing that’s now possible online.

Instead of simply consuming information, users create it themselves and share it with others.

Examples of Web 2.0 sites include the user-created encyclopedia Wikipedia, the photo-sharing site Flickr, social networking sites like MySpace or Facebook, blogs, and now SAMHSA’s own Homelessness Resource Center at www.homeless.samhsa.gov.
