I have listened to probably 10 of these, and most are really interesting, really insightful. Some of the guests don't really speak to me, but that's the nature of anything, right? My one complaint: many of these items are only offered as videos, which makes them 500MB, thus taking an hour to download one item. Maybe if you're a student on a college campus you have massive bandwidth, but the rest of us...not so much. It would be wonderful if you had a choice: video, OR audio only. That aside, this is a wonderful series that Stanford has been doing for a decade, and to be able to access this kind of treasure via the internet, for free, is fantastic. Thank you Stanford, Hilton, and all of the writers who give their time.
