Great points! Although in a truly decentralized system, users wouldn’t need to seed everything—only the posts or comments they upvote. This would give upvotes more weight, as users would be actively supporting and “hosting” content with their compute resources.
No mutability required. Unpopular posts and comments fade when the OP (seeder) goes offline.
No need for real-time messaging or extensive message histories—it could be “survival of the fittest ideas.” Popular content stays seeded, while less popular content disappears when the poster goes offline.
