Web 2.0
The World Wide Web 2.0 extended earlier work without displacing it,
including active content, user interactivity, and a more tailored interactiv-
ity suited to a personalized consumption of data. Read-only content was
transformed into community-developed content in Wikis, together with
shared communication in blogs, threaded discussion systems, and com-
munity portals (see Figure 8.3). Communication streams ceased being
pull-only content accessed by directed action, evolving instead to push-
form alerts and announcements from subscriptions in Twitter, friends in
Facebook, or reputation referrals in LinkedIn.
Web 2.0 technologies include all of Web 1.0's capabilities but allow
consumers opportunities to tailor their information feeds and to search
more efficiently using large data aggregation engines such as Google,
Bing, and AltaVista. This is the realm in which my conversation with the
Portuguese individual becomes possible, because Web 2.0 technologies
facilitate user-responsive data expression and a more interactive environ-
ment for interchange.
