The rise of Twitter

There are now two hundred million people who have Twitter accounts and the amount of Tweets being submitted through the site now exceeds three hundred and fifty billion tweets every day, which takes some doing! Yet we must not forget that this site is just five years old and the growth has been more recent than that, because at first people did not seem to understand the concept off writing and sending messages with just a hundred and forty characters, but they do now!
