It's a packed show this week, including the nitty and the gritty from Kevin Rose, founder of social aggregating websites Digg and Pownce. We also quiz MySpace co-founder Tom Armstrong about the service's new look – and ask him all the questions you wanted us to ask. Listen in to find out what Rose had to say about MySpace's future demographic, its plans for new dimensions and what's happening with its back end.

All this plus the news, your views from the blogs, and an interview with the organisers of the forthcoming BBC Mashed un-conference in London.
