Twitter (www.twitter.com) has become kind of a popular culture punch line. It's often used as a shorthand to represent how self-obsessed and self-involved the American culture has become, and while Twitter does lend itself to a kind of needless sharing, it also has some potentially useful features. Twitter is a microblogging service that allows users to post and read 140-character status messages. These short bursts of information, called tweets, can be anything from what someone had for lunch to feedback on a live event, like a presidential press conference. Much of the library literature focuses on Twitter as either a patron outreach tool or as a way to collect patron feedback.

This article highlights the tremendous potential of Twitter as a research tool.
