Indeed but why would we need substack, if Medium just acted as we know it could, for the benefit of all. To me substack and all the other platforms are just more of the same, demanding more of our attention, more of our energy.
Hence why I just stick by Medium, I still think it has most potential to do the right thing, by becoming a solar powered community itself.
I remain quietly hopeful it is in process of being assimilated by the solar powered Ai :)
