When listening to this talk I did have a moment of 'wtf' on the "Start a podcast" part. It's clearly a big part of Kevin's success - the whole rockstar celebrity diggnation thing. But how good are podcasts now? Any startups finding them effective? Or am I just biased because I have no attention span to listen to them, so automatically discount them? How about online video? Back when digg was young, podcasts were the thing; is video today's equivalent, or is it just 'being interesting on Twitter'?
