According to Wikipedia, Twitter is a free social networking and micro-blogging service that enables its users to send and read other users' updates known as tweets. Tweets are text-based posts of up to 140 characters in length which are displayed on the user's profile page and delivered to other users who have subscribed to them (known as followers). Senders can restrict delivery to those in their circle of friends or, by default, allow anybody to access them. Users can send and receive tweets via the Twitter website.
Estimates of the number of daily users vary, because the company does not release the number of active accounts. In November 2008, Jeremiah Owyang of Forrester Research estimated that Twitter had 4-5 million users. A February 2009 Compete.com blog entry ranked Twitter as the third most used social network (Facebook being the largest, followed by MySpace), which puts the number of unique monthly visitors at roughly 6 million and the number of monthly visits at 55 million, however only 40% of users are retained. In March 2009, a Nielsen.com blog ranked Twitter as the fastest-growing site in the Member Communities category for February 2009. Twitter had a growth of 1382%, Zimbio had a growth of 240%, followed by Facebook with a growth of 228%.

According to Wikipedia, "Facebook 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."
