Twitter, a microblogging service less than three years old, commands more than 41 million users as of July 2009 and is growing fast. Twitter users tweet about any topic within the 140-character limit and follow others to receive their tweets.

Our method finds distinct influentials who are not discovered by other methods.

Our study reveals that the presence of "reciprocity" can …
