why do it? To borrow from the site's About pages: "First, it will help you find shows that others have not only watched, but are talking about. Hopefully it'll throw up a few hidden gems. People's interest, attention and engagement with shows are more important to Shownar than viewing figures; the audience size of a documentary on BBC FOUR, for instance, will never approach that of EastEnders, but if that documentary sparks a lot of interest and comment - even discussion - we want to highlight it. And second, when you've found a show of interest, we want to assist your onward journey by generating links to related discussions elsewhere on the web. In the same way news stories are improved by linking out to the same story on other news sites, we believe shows are improved by connecting them to the wider discussion and their audience." Dan Taylor explains Shownar from the BBC's perspective

"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.
