If you enjoyed John Siracusa's epic OS X 10.7 Lion review, then you should be aware that he does a weekly podcasts on Dan Benjamin's 5by5 podcasting network called "Hypercritical". The most recent episode of Hypercritical, called "Nakedly Optimistic", serves as the first episode in what will probably be a couple episodes that covers his review in more depth (if that's even possible). John covers the details he wasn't able to get to, due to the uncertain deadline he was under depending on when Lion was released to the public. He covers a few mistakes he made, and provides a bit of follow-up to some of the comments he's seen regarding the review. I highly recommend you listen if this sort of thing excites you.
