Fifty million Tweets a day.
Tweets are messages, containing 140 characters or less, that people send out over the social networking site Twitter.
When you sign up and start Twittering, your tweets are made public and are both presented briefly on the home page of the site, and searchable by other users.
If a user tries to follow your tweets, you will have to give permission before they can see anything you've written.
Substituting all-caps for shouting, the same overwhelming hyperbole slamming the tweets of celebrities goes on 24/7.
