You have a Twitter account. You’ve learned the lingo, you know how to tweet, you keep everyone updated. But you know there’s more than just sending tweets and trying to keep up with your twitstream.
Third-party developers have created an array of applications to help (almost 300K at last count), whether you need to run Twitter in a corporate environment; find out what others are saying about you, your company, or your product; use Twitter on your desktop or mobile phone; read event tweets; add widgets to your website…the list is almost endless.
(Some people started calling this presentation "The Zen of Twitter" :-) )
