Bluegreen has recently joined the twitterati and is now on Twitter as @bluegreenland. What is twitter? Twitter is an easy to use, real-time messaging system for groups and friends. Another way to think of Twitter would be to think of it as a text messaging (or instant messaging) service. You can send short text messages (up to 140 characters) to one person or to many people. Everybody who is "following" your Twitter account can see your messages, except for "direct messages" that you can send and receive from other people who follow your account on Twitter.
