Twitter: It Really is All About You, Sharon Gaudin, Computerworld via PC World (Oct 3)
New study of tweets shows once again that Twitterers aren't talking about anything important - their tweets are mainly about themselves. But some (about 20%) do post informational messages - these people "tend to have larger social networks and interact more with their followers."
There is also potential for more serious or intentional use of twittering.
"Astronauts used Twitter to communicate from space, tweets have been issued from the White House, and Twitter turned into something of a lifeline for the people of Iran during the recent government crackdown over disputed elections there."
