The show is far from informative or even insightful, but that was never really the point. It didn't take long for the show to diverge from its premise (top stories from the social news website digg.com). It's really just about the chemistry and personalities of the hosts, which I find very enjoyable. And still, there have always been the occasional insights (albeit perhaps biased and not "fair") on the start-up world, gadgets, internet media, etc.
Oh, and there are some completely ridiculous "best of" moments that are likely to induce intense laughter. Like this: http://www.youtube.com/watch?v=71Zpl6tmUxs&feature=playe...

Even if Digg wasn't super profitable, it was definitely influential and popular not too long ago.
