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.
