Diggnation is pretty much the only video podcast that I watch regularly. It is essentially two guys sitting on a couch, shooting the breeze, and drinking beer, which may not be to everyone's taste but is right up my street. I've looked once or twice at digg - the "user driven social content website" that it is apparently about but I've never really got it unlike the show.
I was astounded to read BusinessWeek's breathless estimate that co-presenter and Digg founder Kevin Rose stands to make $60 million out of it. That is worth a drink or two.
