Twitter, the popular microblogging site, is not just for individual communication. Businesses, such as Home Depot, Southwest Airlines, and Whole Foods Market use Twitter to promote their products and provide customer service.
At its core, Twitter is simple: type a short message of up to 140 characters to tell people what you are doing. However, it does have its own unique language that can take some time to learn.
To help businesses use Twitter, Twitter has published Twitter 101. This site shows how to create a Twitter account, how to follow other users, and how to create posts. It features a very helpful guide to Twitter best practices, and most importantly, a list of case studies showing how companies actually use Twitter.
In today's business environment, having a presence on social networking sites is becoming just as important as having your own website. Twitter 101 is an excellent tool to get started.
