Thank you, Mark, for a great podcast. I've listened to it twice already and appreciate the great information on refining my espresso extractions. I've had a long journey on my way to great coffee and am continuously learning. Your 5 "M's" is a must listen for anyone looking for the elusive "Godshot" or, at the least, a better extraction. I've been a fan of the podcast virtually since it's inception and credit much of my basic knowledge and skill to points I've picked up from the podcasts. The science and explanations of why things should be done a particular way or why certain things are more important that others help us understand the science and reasoning without accepting techniques or suggestions on blind faith. While many of the discussions about the coffee industry and SCAA are interesting for many, they don't add to the quality in the home enthusiast's cup. This podcast brings it back to the early shows for the newbie or home enthusiast not in the coffee industry.
Like many other subscribers, I do miss the frequency of the podcasts, but appreciate and savor each one that comes out. Although this podcast lasted over an hour (portafilter podcast competition?), the information provided was incredible. Make them as long as you need, with as much great content that you can pack in!
Thank you again for everything that you do for the coffee community and to it's enthusiasts. Your efforts and contributions are treasured and appreciated!
Mark: Your podcasts are like godshots - few and far between, but when they happen they feed the soul.
However you once again mangled the definition of P.I.D.
According to my Controls Theory textbook (Ogata) from third year Electrical Engineering, P.I.D. stands for Proportional - Integral - Derivative control, not Progressive Integral Derivative
According to my Controls Theory textbook (Ogata) from third year Electrical Engineering, P.I.D. stands for Proportional - Integral - Differential control.
I haven't listened to Mark's podcast, but I've found plenty of sources that say PID = proportional–integral–derivative (e.g., PID controller on wikipedia and Proportional-Integral-Derivative control from Carnegie Mellon's PID tutorial). On the other hand, the Free Dictionary lists "PID" as an acronym for Proportional - Integral - Differential and Proportional - Integral - Derivative (link).
A comment concenrning the technical quality of the podcast (ie. not the content): Awful. Mp3 with average bitrate less than 64kb/sec sounds terrible. I'm not looking for a Hi-Fi experience here, but at this slow bit rate, the sound is full of mp3 packing artifacts which makes it tiresome to listen.

Mark, Podcast 61 is a tour de force. It's one of the best I've listened to (haven't heard them all). You've done a stellar job of taking on one of the central challenges that CG faces: creating a thriving community that satisfies all levels of "geek," enables those at each level to continually better their coffee/espresso and paves the way for productive interaction between and among all concerned. Nice job.
