This week we have a pair of fascinating interviews from two technological thinkers at the top of their game.
First up Kevin Anderson speaks to the writer and communication pioneer Howard Rheingold, doyen of virtual communities and author of the influential tome Smart Mobs.
Then Kevin talks to interface designer Aza Raskin, of Mozilla Labs - the place where the creators of Firefox work on new, experimental projects.
Plus, Bobbie Johnson catches up with all the week's tech news and your posts.
