great point. IMO, there are a few things that are needed at the technical level for a system like this to work. - identity - a common id system across the whole system that supports all existing means (think oauth based) - a mechanism to sign your messages to prove that you truly were the poster (since there is no longer a central authority to validate that) - a mechanism to store these messages and get them in real time (this is where activitypub can be super handy) - a way to search / index these messages for retrieval - a way to create a feed of activity that uses some algorithm for ranking - a way to discover other forums / communities so while activity pub serves well for one aspect, the other ones aren't quite there yet to be used in a decentralized fashion.
