Pattern One : Harnessing Collective Intelligence

Web 2.0 in this pattern

Web 2.0 is the new version of web, which is different from previous Web 1.0. There are many improved aspects from Web 1.0. Web1.0 is mainly used to publish information through World Wide Web by publisher without or less interaction with user or reader. In the other hand, Web 2.0 inspires reader to contribute the content of website and could collect their intelligence and ideas to solve some tasks. Therefore, the pattern of harnessing collective intelligence would be the main feature of Web 2.0 and a exact sample of Metcalfe’s law which is used to descript network value. As Wikipedia descript,” Metcalfe’s law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). ”  There are some main insight points of this pattern:

  •  Reward user

Users hope to get award or encouragement after they post there content to the net, so many famous website use levels or virtual money to reward to them.

  •   Provide meaningful context

The context of the web must encourage the use to do contribution. If there is no framework or community context for user, nobody will post information into it.

  •   Trust your users

The collective intelligence pattern needs user to do contribution to your website. If you do not trust your user nobody will do contribution at all.

  •  Create more channel to help user’s participation

User may hope to use diversity channel to access your web to do contribution,for example by mobile devices or laptop.

Some cons of the pattern

  • Privacy:  Privacy for internet is a important issue, especially for Web 2.0, a more user-contribution net environment.
  • Quality: The content quality of user provided may not fair to all user.

Evaluating Web 2.0 application

Twitter ( is a popular tools today to share information. User could post there news or pictures as their contribution.  “it has been used to organize protests, sometimes referred to as “Twitter Revolutions“, which include the 2011 Egyptian revolution, 2010–2011 Tunisian protests, 2009–2010 Iranian election protests, and 2009 Moldova civil unrest” . ( “Could Tunisia Be the Next Twitter Revolution?” 2011) Twitter reward user by user classification and follow number and they always trust his user and contents. Meanwhile the context of contribution is more coherent and consistent with social network in the really world. Twitter has developed many channel by “#” to allow user to do access and contribution. In the privacy and quality domains, they established some rules and verification logic to prevent issue in the first stage. Traditional blog applications lack the interaction methods comparing with Twitter. In the future , Twitter’s application would become more portable in multi-platforms.
