What do you do on twitter?

[Sreedev]

Hi, Twitter is a social network used by millions of people, and thousands more are signing up every day to send short messages to groups of friends.
Here, you can write short updates, often called "Tweets" of 140 characters or fewer. These messages are posted to your profile, sent to your followers, and are searchable on Twitter search.

Following someone means you've chosen to subscribe to their Twitter updates. When you follow someone, every time they post a new message, it will appear on your Twitter home page. You can search for people by name or user name, import friends from other networks, or invite friends via email. You can also follow some of the people we've suggested.

Hope this helps!
