I've been wondering the same thing, Rolli.
Why assemble a paid research panel when some of us have been sending detailed feedback for over two years to no avail? For the longest time, I viewed Medium as a creative community but it has been overrun--and run over--by greedy grifters on the make and now even new followers are bots.
In addition to that, the scamming is off the charts and has spawned so many wannapreneurs the mind boggles. How many folks are funnelling their last credit card dollars into a Medium membership hoping to pull themselves out of hardship? How many more are paying through the nose for ebooks, writing academies, and the like?
On another note, are you familiar with hitrecord.org? If so, thoughts?
