Oh, I did not get that. That’s an interesting idea. Would still need to solve the ‘where’ do I post (which for many seems to also mean ‘to what Instance do I belong’), and then how do one moderate content from various communities, from posters that may or may not adhere to one’s own rules. It won’t be obvious but I would be more than willing to see something like being experimented, even if it’s to decide it’s too complex, it seems worth at least an attempt, imho.
