"Shownar tracks millions of blogs and Twitter plus other microblogging services, and finds people talking about BBC telly and radio. Then it datamines to see where the conversations are and what shows are surprisingly popular. You can explore the shows at Shownar itself. It’s an experimental prototype we’ve designed and built for the BBC over the last few months. We’ll learn a lot having it in the public eye, and I hope to see it as a key part of discovery and conversation scattered across BBC Online one day." Matt talks about Shownar on Pulse Laser.
