For a programme that's only been going for 4 weeks Question Time Extra has already managed to draw in some of the blogosphere's big names for its continuation of the real Question Time debate on News 24 after the main event. Iain Dale, our own dear Alex Hilton and yesterday little ol' me have been on now. As a show constructed around viewer's responses though, the real stars are the audience. Yet Radio 4 presenter Eddy Mair argues that there is too much interactivity on the beeb. "What makes listeners or viewers or, heaven forbid bloggers think they have the faintest idea about broadcasting?" he demands.
