We met Guppy in person once. Like you I think his methods can be a bit obvious but he certainly seems to have the results. I've subscribed to his newsletter for a long time and even though I don't read it much now it's dirt cheap so I can never quite bring myself to cancel it.
Anyway he writes like a pratt but surprisingly in person he seems to be a pretty nice guy with hardly any of the pretentiousness which comes out both in his writing and his facial hair.
