We already know that users ask a lot of questions on Twitter. The short format and @replies make it conducive to asking questions and getting quick replies, but have you ever wondered which accounts get asked the most questions?

Our good friends at Column Five created this infographic that was published by InboxQ. The infographic outlines which accounts receive the most questions, and like we’d expect it’s mostly people who are constantly in the limelight. In fact, Justin Bieber, the teen prince of pop, receives 16 percent of all of the questions asked to the top 100 actors, actresses, sports stars and other notable figures who are asked the most questions on the microblogging service. Lady Gaga falls behind him and receives 7 percent of questions asked towards musicians in the top 100.

Other accounts, like Xbox Support (@xboxsupport) are stars in their categories as well. Xbox Support receives 27 percent of all questions to support accounts, with @blackberryhelp and @twitter falling behind. Barack Obama unsurprisingly receives a lot of questions as well. He receives 100 percent of the questions sent to politicians, as no other politicians are in the top 100 most asked profiles.

Are you surprised by any of the stats?
