Twitter is an information network made up of 140-character messages called Tweets. It could be defined as a crossover between microblogging, instant messaging and social networking.
Many tweets answer the question of what the user is doing, others are responses to other tweets, pointers to online resources that the user found interesting, musings, or questions.
Similar to social networking sites like Facebook, Twitter lets users collectively establish numerous and interconnected networks of users.
