BBC Connected Studio are running an event in The MAC on Tuesday 23rd February to attract ideas for the Future of Content
If you aren't aware of BBC Connected Studio - they run an initiative to enlist small companies to present ideas around a brief and then pay to implement the best candidates as a functional demonstration (usually within a few months). These demonstrations (if they are web-based) are often then made public via the BBC Taster site http://www.bbc.co.uk/taster/ where it gets tonnes of live feedback.
Do consider this, as they are looking for really new or strange ideas, and unlike most 'innovation events' there doesn't need to be an obvious cash-profit plan.
This is on the one day I'm out of Belfast next week
However, obligatory plug for the "Your Story" taster, as it's related to my day job: http://www.bbc.co.uk/taster/projects/your-story-2
