The third key element of Web 2.0 systems is the concept of social networks, community, collaboration and discussion. People naturally want to communicate, share and discuss; this communication is a key part of understanding, learning and creativity. The unique element that Web 2.0 brings is that of social networks and community which are typically enabled by blogs, discussion groups, and wikis. In Web 2.0, the sheer scale and number of people on the Internet creates an "architecture of participation" where the interaction between people creates information and systems that get better the more they are used and the more people who use them. This harnessing of the collective intelligence creates systems which have more and better information than any one person could generate; it provides the "wisdom of the crowds."
