Social Networking Services

Classmates.com

Is a social network service created in 1995 by Randy Conrads who founded Classmates Online, Inc. The social media website helps members find, connect and keep in touch with friends and acquaintances from throughout their lives — including kindergarten, primary school, high school, college, work and the United States military. Classmates.com has more than 40 million active members in the United States and Canada. Nielsen Online ranks Classmates as number three in unique monthly visitors (U.S. home, work) among social networking sites.
Reactions:They can write emails and send them, but the recipient cannot read them unless the sender becomes a paid member. This doesn't become apparent until an email is already composed and sent.
Face book
Is a free-access social networking website that is operated and privately owned by Facebook, Inc. Users can join networks organized by city, workplace, school, and region to connect and interact with other people. People can also add friends and send them messages, and update their personal profiles to notify friends about themselves. The website's name refers to the paper facebooks depicting members of a campus community that some US colleges and preparatory schools give to incoming students, faculty, and staff as a way to get to know other people on campus.
Mark Zuckerberg founded Facebook with fellow computer science major students and his roommates Dustin Moskovitz and Chris Hughes while he was a student at Harvard University. Website membership was initially limited to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It later expanded further to include any university student, then high school students, and, finally, to anyone aged 13 and over. The website currently has more than 175 million active users worldwide. Facebook recently surpassed Myspace in amount of visitors, making Facebook the most popular social network, followed by MySpace and Twitter.
Facebook has met with some controversy over the past few years. It has been blocked intermittently in several countries including
Syria and Iran. It has also been banned at many places of work to discourage employees from wasting time using the service. Privacy has also been an issue, and it has been compromised several times. It is also facing several lawsuits from a number of Zuckerberg's former classmates, who claim that Facebook had stolen their source code and other intellectual property
Raections: Users may choose to join one or more networks, organized by city, workplace, school, and region. These networks help users connect with members of the same network. Users can also connect with friends, giving them access to their friends' profiles.
The website is free to users, but generates revenue from advertising. This includes banner ads, users can create profiles including photos and lists of personal interests, exchange private or public messages, and join groups of friends. By default, the viewing of detailed profile data is restricted to users from the same network and "reasonable community limitations".

My Space
Interactive, user-Is a social networking website with an insubmitted network of friends, personal profiles, blogs, groups, photos, music, and videos for teenagers and adults internationally. Its headquarters are in Beverly Hills, California, USA, where it shares an office building with its immediate owner, Fox Interactive Media; which is owned by News Corporation, which has its headquarters in New York City. In June 2006, MySpace was the most popular social networking site in the United States. According to comScore, MySpace was overtaken internationally by main competitor Facebook in April 2008, based on monthly unique visitors. The company employs 300 staff and does not disclose revenues or profits separately from News Corporation. The 100 millionth account was created on August 6, 2006 in the Netherlands and the site counted approximately 106 million accounts on September 8, 2006,
Reactions:MySpace operates solely on revenues generated by advertising as its user model possesses no paid-for features for the end user. Through its Web site and affiliated ad networks, MySpace is second only to Yahoo! in its capacity to collect data about its users and thus in its ability to use behavioral targeting to select the ads each visitor sees.
