Ask Patti Smith, Sir Martin Sorrel, Robert Redford or any Cannes Speaker a question via twitter

Fancy asking one of the speakers in Cannes a question? Want to know what Sir John Hegarty or Chuck Porter thinks about something? Want to know Martha Stewart or Pharrell Williams take on creativity? You can ask them questions by tweeting - using the hashtag #CannesQ . If twitter isn't your cup of tea, you can also ask via the Cannes Lions Facebook page, either as a message or as a video. Yes, as video! If you want to make a video question, just upload it to your own YouTube account and then either Tweet the link (again using the #CannesQ tag) or put the link on the Cannes Lions Facebook page. Ta-dah. Philip Thomas, the CEO of Cannes Lions give a quick how-to here.
