Matt, you know I love what you & the FIRSTCasters are doing...so, no offense, but are you really going to get a true response on any specific person as a guest on a public forum?
I find listening to JVN and Karthik talk to be very interesting, but if I wasn't interested, I'm not going to publicly post and say I don't want to listen to them...not only are they readers on the forum, but we are a community that is naturally skewed towards being extra-gracious...thus, non-response is not as clear as it should be (it should be "I don't care enough to respond", not "No, I don't want to hear them" or "I don't care enough to respond", with no idea as to what percentage of each).

This goes with anyone listed as a potential guest previous to air.

As for the other suggestions, I would suggest researching the average length of older, more popular, but similar genre podcasts before changing the length. Because of audience similarities, you may be able to find the optimum length for your segment without messing with the length much.
