That's what I'm calling my little experiment in podcasting. It's just me, no music, and the basic idea is to look back over some of the past week's topics on this blog, with full freedom to digress.
ADDED: It's about 26 minutes long.
MORE: A problem with a podcast is that you can't do updates and make corrections. I see that I quoted this line from a recent blogpost: "It had been widely assumed until recently that human evolution more or less stopped 50,000 years ago." But for some crazy reason I said 500 instead of 50,000. Well, that's a slight discrepancy!
