I'm listening to a podcast, 2015-05-31 where, you, Ian are attempting to read an article about an Unusual Norwegian Prison. As usual, Mark is interrupting after your every 5th word. I actually like the guy but his constant interruptions using an agitated tone are really a turn-off. Sometimes I have to switch to something else less grating just to get away from what borders on insanity.
Calm the dude down!! He is very intelligent and often interesting but he may be better suited to preaching from an outdoor soapbox where his voice might disperse into the open air.
I apologize in advance if my comment is insulting. It isn't meant to be. I hope my criticism is constructive.
Thanks and I DO enjoy your show more often than not.
