Featured Doer: Ashton Kutcher

The race was on. One year ago, Kutcher was facing-off against CNN to see whose Twitter account would reach 1 million followers first and, after a battle that entranced web nerds and celeb fans alike, Ashton emerged victorious. He streamed his celebration live on the Web, he's planned dinner with his wife via Twitpics, and he's used his social media fame to address sex trafficking--proving he's the celebrity king of leveraging social media.

His production company, Katalyst, has been named one of the ten most innovative by "Fast Company" and made TV shows and Web series for almost every major network and an array of cable channels.

He is one of 15 candidates for a video interview in our HuffPost Spotlight Series, presented by HP. The top five question-getters will be interviewed using your questions.

Question submissions for the Spotlight Series are now closed. Thank you for your questions and stay tuned for our interviews with the top five question-getters!
