> What public space offers infinitely scalable many-to-many communication? Public space is distance limited, these platforms aren't. Just because these platforms chose not to heavily regulate the content doesn't preclude their ability to ever do so in the future, nor does it make a comparison to a theoretical public space that never existed any more valid. You're still extremely limited on Facebook and Twitter by natural space and time constraints. Just because these take a slightly different form and aren't based on physical distance between communicating parties doesn't mean that communication on the platform is just completely unfettered. So "infinitely scalable" does not mean that each person can actually consume all content produced by all other people. That's not possible in all current iterations of social media and presumably is fundamentally unachievable. Rather, it means the system can scale to an arbitrary number of producers and consumers, each of whom is still subjected to natural physical constraints, whether those be determined by physical location, screen space, the loudness of your voice, the speed at which you read, the speed at which you type, etc.
