Many tech industry influencers think of Twitter as little more than a vehicle for extending the reach of their opinions. However, Twitter offers more to influencers than a bigger audience. It can be an aide in strengthening expertise as well. Combining the two agendas — improving expertise and expanding reach — makes good sense. One influencer who’s doing this is John Moore, founder of Chilmark Research.

John is a veteran industry analyst and an opinion leader on IT in the healthcare market. He was recently ranked in the top 50 tech industry analysts on Twitter, in a project using Edelman’s free measurement tool TweetLevel (see earlier post).

He provides a clear description of why and how he uses Twitter, including four tips based on his own experience:

• Do not write off any technology completely
• Define your purpose
• Choose who you follow carefully
• Be engaged and engaging

Check out the complete post. It’s one of the best explanations I’ve seen for people who are serious about managing their expertise and the reach of their opinions.
