For Mobile Monday which I co-organise, I built a new Backchannel. Backchannels are a screen, next to thepresentation, where people in the audience can post their reactions. Our new backchannel includes posting by Twitter, SMS and photo’s via Mobypicture.
To post via Twitter, people had to include the hashtag #momo in their posts. The event was a big success, and #momo even made it to the trending topics on Twitter search!
I’m already talking to some other events, who want to use this to enhance audience participation.
