Twitter is a microblogging platform that allows users to post short updates of up to 140 characters. It functions like a cross between instant messaging and an online chat room. The largest demographic of Twitter users are 35-44 year olds. People use Twitter as a virtual water cooler to engage in conversations and build online communities. Marketing via Twitter can help engage customers, monitor brand mentions, and provide live updates on events. Setting up a profile, learning how to post, follow others, retweet, and use hashtags are important basics for using Twitter effectively. Objectives like networking, monitoring brand mentions, and extending the reach of content can be achieved through strategic Twitter use.
