Okay, maybe not the world, but the Twittersphere at least. The pop sensation tops Forbes list of the most influential Twitter celebrities based on his Klout score.

A play off the word “clout,” Klout measures how influential a tweeter is online by measuring a number of factors: Your number of followers, how quickly and often someone will be retweeted, frequency of tweets and how influential the other people in your network are (i.e. if they’re important, they boost your score).

Biebs comes in with a perfect score of 100 at press time. It’s easy to see why. His @justinbieber account is very active, he gives information not only about his personal life but also his upcoming projects and concerts, has a slew of celebrity friends/followers and engages with his fans by responding to their tweets.

Bieber tops two Jonas brothers, President Barack Obama, the Dalai Lama and even Lady Gaga when it comes to Twitter influence.
