I'm in a cluster of Internet radio podcasts this week.

Cameron Reilly hosts "G'Day World," a Melbourne-based podcast covering science, technology, politics and media. G'Day World was Australia's first podcast, and has been active since 2004. Cameron invited me to chat for a bit as part of the lead-in to September's Singularity Summit.

It's one of those conversations where I thought I stumbled, but Cameron seemed happy with it. In any case, it's not my best podcast example, but it does bring up some interesting topics.

R.U. Sirius invited me back to serve as co-host for his shows this last weekend, and two have now appeared as MP3s.

The first is an extended conversation with Steve Wozniak on Neofiles, primarily about the various large and small pranks he's pulled on friends and strangers over the years. Some are pretty amusing, but I suspect that most work better in the moment. I was a bit disappointed to discover, in a post-show conversation, that he's a bit of a climate-change denialist, but I suppose he could have been pranking me at the time.

(To answer the question that seems to be on people's minds this week: no, he didn't have an iPhone yet. He is getting a free one, but it won't arrive until Saturday. I showed him my N800, and he did seem pretty impressed.)

The second, on the RU Sirius Show, covers a mix of topics, starting out talking about the cybermoth story (with Woz sticking around), then a long conversation with David Talbot about his new book on John and Robert Kennedy. Although Talbot's book is a broad examination of the Kennedy legacy, most of the discussion focused on the evidence for a conspiracy around the JFK assassination. I'm more active in the cybermoth story than in the Talbot part, fwiw.

We recorded a third show after Talbot left, me talking about augmentation and cyborgization; I don't know yet when that will be up.
