The cornercutter podcast is really professionally done and offers a variety of interesting segments. I use the cornercutter podcast to stay current on new puzzle releases and world records, but what I really enjoy are the interviews. The host, Josh (a pyraminx enthusiast) invites a nice range of guests, from well known cubers on the forums to high profile YouTube channel hosts. I enjoy learning about competitions, speed techniques, ways to optimize my cube for better functionality. I definitely recommend this podcast.
