I think the important part is "for some folks"; we're talking about implementing a system that attempts to standardize reading behavior when reading behavior and publishing behavior vary significantly. Some readers check-in daily, other readers check-in weekly, some readers check-in once a month. It's almost impossible to track this type of behavior and add any type of weight to that in our currently existing algorithm.
We do understand this and have made adjustments to the algorithms to be more accommodating over time. I'm not really a fan the way this is framed. While you're pointing out that you're not accusing me of being alienating or dismissive, you highlight an example that is incredibly alienating and dismissive for reasons that are beyond me.
I got tagged in this topic, and tried to clarify on alternative options or reasoning behind not building a requested feature. Again, the difficulty in all of this is creating a platform that is able to highlight and surface series that is indicative of what people are reading and engaging with in the present moment. While it is a far cry from being perfect and unable to take into account subject qualifications (such as quality of comments), we are actively trying to make improvements that aren't aimed at punishing creators.
While I am hesitant to disclose further information on how the algorithm functions, inactive subscribers does not negatively penalize creators to an extent that we should be investigating alternative subscriber methods.
