Twitter (www.Twitter.com) is a great tool for sharing, discovering, and connecting with others who care about the same ideas and information. You can use Twitter right on your phone without downloading any software and even with just one teacher cell phone per class, contributions can be made and modeled anywhere, anytime. Twitter has become such a popular tool because it asks one question, "What's happening?" Answers must be under 140 characters in length and can be sent via mobile texting, instant message, or the web.
