We've just spent the weekend alongside the Radio 3 Interactive Team at The Sage Gateshead for a festival of ideas called 'Radio 3 Free Thinking'. We were there to join in with the conversation. Our social media tools of choice were Twitter and Post-it notes, together with a wall on the concourse for the post-its. The question being asked was not so much a 'What are you doing now?' but rather a 'What's the big question for the next 50 years?' in other words less Twitter and more Radio 3.

The festival format provided a lively exchange between contributors and audience that passed without effort onto our Post-it boards. With roughly the same character count between a Post-it note and a tweet we created a kind of low-fi Twitter board that was hugely popular.
