According to the site itself, “Twitter is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?”
Twitter is a microblogging platform – users may publish messages that are no longer than 140 characters, including spaces.  The posts, which may include links, are available to one’s “followers” within a few minutes and remain permanently searchable on the Twitter servers.  Users may send and receive messages directly at twitter.com, through a third-party application, or with a text messaging service.

Twitter is free to use and the basics are easy to learn.  In addition to be a fun way to connect socially, it is a goldmine for the wise internet marketer.  Businesses can identify and connect with potential clients easily in the fast-paced microblogging environment, and the savvy internet marketer is on the cutting edge of this growing technology.
