i think this is cool, i'm happy you did it... i really listen to podcasts for the hosts, though. i think the banter and the personality and the perspective are things that i really enjoy. getting to know people through what they choose to talk about or how they frame things is part of the whole charm.
if i want a fast rundown of HN, i'll read HN. you did make me kind of crave a 15 minute weekdaily "morning news" style podcast with some tech journalists that runs down the most talked about HN posts, though.
