What is twitter??? how it works?

Many social networking Web sites have lots of bells and whistles. Sites like MySpace and Facebook let users build profiles, upload pictures, incorporate multimedia, keep a blog and integrate useful or bizarre programs into homepages. But one Web company with a very simple service is rapidly becoming one of the most talked-about social networking service providers: Twitter.

So what does Twitter do? When you sign up with Twitter, you can use the service to post and receive messages to a network of contacts. Instead of sending a dozen e-mails or text messages, you send one message to your Twitter account, and the service distributes it to all your friends. Members use Twitter to organize impromptu gatherings, carry on a group conversation or just send a quick update to let people know what's going on.

Twitter's history is entwined with a few other Internet companies. Twitter's founders are Evan Williams, Biz Stone and Jack Dorsey. A few years before Twitter was born, Williams created Blogger, a popular Web journal service. Internet giant Google purchased Blogger, and Williams began to work directly for Google. Before long, he and Google employee Stone left the Internet giant to form a new company called Odeo.

Odeo is a podcasting service company. According to Williams, he didn't have a personal interest in podcasting, and under his guidance, the company temporarily lost focus. However, one of Odeo's products was just beginning to gather steam: Twitter, a new messaging service. Stone gave Twitter its name, comparing the short spurts of information exchange to the chirping of birds and pointing out that many ring tones sound like bird calls
