Getting the Most Out of Twitter

The truth is, you don’t have to post a message to get the most out of Twitter. At its best, the social medium is a perpetual, personalized news service about topics of your choosing — whether health care reform, tech news or the latest episode of “Gossip Girl” — filtered and served to you by people who care a lot about what you care a lot about.

Even the most prolific users say Twitter has become more useful as a way to tap in to the discussions of the day than to broadcast their own thoughts.
