How TWITTER works.......???

Many social networking Web siteshave lots of bells and whistles. Sites like MySpace and Facebook let users build profiles, upload pictures, incorporate multimedia, keep a blogand 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.
As the service became a more important part of Odeo, Stone and Williams decided to form a new company with Twitter as the flagship product. Williams bought out Odeo and Twitter from investors, then combined the existing company and service into a new venture calledObvious Corporation. Jack Dorsey joined the team and began to develop new ways for users to interface with Twitter, including through computer applications like instant messaging and e-mail. In March 2006, Twitter split off from Obvious to become its own company,Twitter Incorporated.
