TwitNine

The founders of Twitter made a decision that has helped to make twitter the success it is, they wrote special functions that allowed outside programs (websites and desktop applications) to Access Twitter.These API’s (Application Program Interfaces) meant that people could write widgets that allowed people to automatic post links to blogs on Twitter, or access Twitter from a desktop program rather than a website.
On of the application is “Twhirl” which is a desktop client for the platform Twitter that builds on the very cool Adobe Air. It uses the technique like XHTML/CSS or Flash/Flex.
