It's one thing to be on Twitter. It's another thing to do it. According to a recent analysis of 19 million Twitter accounts by Campbell, CA-based network security company Barracuda Networks Inc, 73% of Twitter registrants have posted fewer than 10 messages, and a third have never "tweeted" at all. But for those who learn the basics of Twitter, it can be a powerful medium for generating personal or corporate brand awareness and credibility. Some simple strategies for those who get the jitters over Twitter are: 1. Use a third-party client. 2. Help yourself go viral. 3. Follow freely. 4. Give due credit.
