Everyone is talking about Twitter! Even news broadcasters tell listeners they can "learn more by going to Twitter." So what is it?
Twitter is a social networking and micro-blogging service that allows its users to send and read other users' updates. It asks the question, "What are you doing?" Then you answer by sending short text messages 140 characters in length, called "tweets" to your friends, or "followers."
The short format of the tweet defines the service provided by Twitter, giving relief from the fatigue of long email and IM use. It allows quick communication with people that you wouldn't normally exchange email or IM with, opening up your circle of contacts.
Your tweets are displayed on your profile page, on the home page of each of your followers, and in the Twitter public timeline.
Twitter is quite new to me, but I am learning. If you have used it, would you please leave a comment and tell how it is useful to you?
