Sad to see that David is going to stop writing. I hope he, or someone else, archives it using a free service. It resonated with me, as I have considered stopping writing here several times over the years. This part particularly stood out:
As a collective (coffee geeks/specialty industry talking heads / starfuckers and starfuckees) we lend too much credence to unbridled theorists. The positive reinforcement from comments, retweets, attention perpetuates this kind of malignant behaviour. It becomes self-fueling, and unfortunately (or fortunately depending on your point of view) it can be rewarding in a roundabout way.
Thought is cheap though. Developing a compelling, yet ultimately shallow narrative is also cheap, and easy (see most TED talks). Action, work, making something, creating change is much more difficult and often less heralded. I hope to do more of the latter and less of the former.
