Wikipedia has become the largest and most popular general reference work on the Internet. It is a free, collaborative, multilingual Internet encyclopedia supported by the non-profit Wikimedia Foundation. Its 20 million articles (over 3.8 million in English alone) have been written collaboratively by volunteers around the world. Almost all of its articles can be edited by anyone with access to the site. Wikipedia allows people to collaborate facts and information and enable the whole world to access this information. There are pro's and con's to Wikipedia, because the information that people enter on there can be made up and manipulated and not always be the truth.

Social network sites (e.g., Facebook, Twitter, LinkedIn in the consumer space as well as many enterprise social software vendors) display a chronological list of human-readable content fragments that describe actions taken by people and applications. For example, in Facebook this capability is referred to as a News Stream. Typically, an activity stream lists status updates from the people in your social graph as well as from applications you have given permission to publish into your stream. That permission might be direct, or indirect (e.g., a “like” gesture results in a subscription subsequent updates).

As Technology is rapidly expanding it means that people today are constantly involved in social networking, being able to upload pictures on the spot and update blogs and tweets on the go. This is all accessable on all smart phones, ipads and all other devices with internet access.
