How many people can you engage if you are only allowed to speak 140 words? Those who are on Twitter, know that in such a case, sky is the limit.

Twitter which started on March 21, 2006 and has more than 284 million users worldwide, has turned into a preadolescent 9 year old today.

Started as an SMS service called 'Twttr', to communicate with a small group by a New York University undergrad Jack Dorsey, it has come a long way from there. Today Twitter is not only used by a major chunk of the world population but also used by organizations, including Governments to break news to people. From India's PMO to NASA all are using Twitter as the next generation communication tool.
