This is a great idea, and is already happening. I did a series of tests/thoughts/reviews on my personal blog last year and linked them in the grinder forum since I found so much of the previous information to be dated and not necessarily consistent with some of the incremental changes that had been made. Versalab M3 Thoughts and Discovery
That drew immediate criticism from some, though I feel I clarified any points and was transparent. AFTER those posts, John, from Versalab, and I had a series of long conversations regarding my thoughts on the grinder, and it's current standing in the market. At that point, we started to working together and I have been providing real world, home-barista feedback that has gone directly into the M4, as well as testing with a refractometer, making some videos for Instagram and YouTube, etc. so, at this point, I am somewhat of a partner or beta tester with Versalab.
I have also been testing some of the new components such as the new control board (which makes a great improvement) and SSP burrs. I was hoping to share some of the findings in the near future, but in full honesty, I have been hesitant knowing the second I do so, users may flag as a "vendor commenting in the main forums", bias, etc., regardless of the fact that many of the moderators regularly post findings of new equipment they have on loan from the manufacturer or distributor. That's a separate discussion, that I don't want to derail this thread with, but felt it necessary to address to provide context.
So, I hope that I can clarify any messaging and provide any feedback or answer any questions you may have to further the understanding and serve the HB community that I've learned so much from, including a lot of those HB reviews others have done before.
