In this proposal, interactivity would happen within the community apps (discord, slack, forums, whatever new ones are built in the future) and not over the protocol. You use a reading app to get a feed with posts with the various communities you're in, and if you want to leave a reply/reaction, you click on the post and get switched to the relevant app/website.
