Marketing / Social networking
Social networking is the grouping of individuals into specific groups, like small rural communities or a neighborhood subdivision, if you will. Although social networking is possible in person, especially in the workplace, universities, and high schools, it is most popular online. When it comes to online social networking, websites are commonly used. These websites are known as social sites. Social networking websites function like an online community of internet users. You can easily begin your search from hundreds of networking communities to join by performing a standard internet search. Social Networking In Plain English (Video)
The Two Biggest
  Facebook
- A social networking website launched in February 2004 and operated and privately owned by Facebook, Inc. Users can add people as friends and send them messages, and update their personal profiles to notify friends about themselves. Additionally, users can join networks organized by workplace, school, or college. The website's name stems from the colloquial name of books given to students at the start of the academic year by university administrations in the US with the intention of helping students to get to know each other better. Anyone age 13 or older can become a Facebook user.
  Twitter
- A social networking and microblogging service created in 2006 by Jack Dorse that enables its users to send and read other user messages called tweets. Tweets are text-based posts of up to 140 characters displayed on the author's profile page. Tweets are publicly visible by default, however senders can restrict message delivery to their friends list. Users may subscribe to other author tweets - this is known as following and subscribers are known as followers. As of late 2009, users can follow lists of authors instead of following individual authors. All users can send and receive tweets via the Twitter website, compatible external applications (such as, for smartphones), or by Short Message Service (SMS) available in certain countries. While the service is free, accessing it through SMS may incur phone service provider fees.
