Lot of people complaining about the interviewer's skill - yes it is different and it can feel like stoned teenager with disorganized thoughts asking questions that form mid sentence :) - but if you give it some space, let it be, it's not bad at all. I actually like the slower pace and very down and dirty style of questioning - as opposed to the fast, high level, polished way that becomes inaccessible some times.
I hope Lex stays this way. The only interview podcast I know of where most of the focus is on the guest. The way he talks, listens and follow up on what the guest says lets me fully engage in the thoughts of the interviewee.
If you are interested in something similar that focuses more on engineering and science and goes far more in depth then I highly suggest Omega Tau (http://omegataupodcast.net/category/podcast-en/) by far the best podcast I have ever found.
