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.
