I think the next sea change of behavior will be when @Mastodon, #bluesky and @threads are bridged, and a Groups protocol matures. They will provide a kind of selectivity of topic, qualifications, and behavior. People are welcome to lurk, but what and how they engage will drive popularity.
@shoq Yes! And the Fediverse has the chance to play a key part in bringing this together, and establishing the values and culture - hopefully in a good way
