MarketingMarketing
 Web 2.0 is used by companies, non-profit organizations and
governments for interactive marketing. A growing number of marketers
are using Web 2.0 tools to collaborate with consumers on product
development, customer service enhancement, product or service
improvement and promotion. Companies can use Web 2.0 tools to
improve collaboration with both its business partners and consumers.
Among other things, company employees have created wikis—Web
sites that allow users to add, delete, and edit content — to list answers
to frequently asked questions about each product, and consumers have
added significant contributions. Another marketing Web 2.0 lure is to
make sure consumers can use the online community to network among
themselves on topics of their own choosing.[45] Mainstream media
usage of Web 2.0 is increasing. Saturating media hubs—like The New
York Times, PC Magazine and Business Week — with links to popular
new Web sites and services, is critical to achieving the threshold for
mass adoption of those services.[46] User web content can be used to
gauge consumer satisfaction. In a recent article for Bank Technology
News, Shane Kite describes how Citigroup's Global Transaction
Services unit monitors social media outlets to address customer issues
and improve products.[47] According to Google Timeline, the term Web
2.0 was discussed and indexed most frequently in 2005, 2007 and
2008. Its average use is continuously declining by 2–4% per quarter
since April 2008

Advantages and disadvantages of web 2.0Advantages and disadvantages of web 2.0

"Nobody really knows what it means... If Web 2.0 for you is blogs
and wikis, then that is people to people. But that was what the
Web was supposed to be all along... Web 2.0, for some people, it
means moving some of the thinking [to the] client side, so making
it more immediate, but the idea of the Web as interaction between
people is really what the Web is. That was what it was designed
to be... a collaborative space where people can interact."
