Twitter

As Twitter is a fast growing tool for communication, it allows people to stay connected and share information instantly. The advantage is that the people can follow others around and get the information that is relevant to them. Another advantage is that you can follow celebrities and relevant topics. The disadvantage is identity theft where people can pretend to be someone else. In addition, tweeting limits you to 140 characters, that some people view it as an advantage as it is short and succinct.
