Example: "She uses Twitter to follow the lives of her friends, as well as her favorite celebrities."

Twitter is a service that allows people to stay connected with each other by answering the basic question, "What are you doing?" Once you sign up for a Twitter account, you can post your own updates, or "tweets," using a computer or cell phone. You can also view the updates posted by other users you are following. Since each tweet is limited to 140 characters or less, the updates must be short and sweet. However, you may twitter as often as you want, meaning there is no limit on how much information you can share.
