@flancian More networks should implement ActivityPub, even if they are themselves not open-source/AGPLv3. I don't see any reason why any new social network (like that Glass one that recently popped up) shouldn't do that to instantly gain access to an established userbase.
@Gargron totally, it doesn't make sense for up and comers in particular, so I agree that long term the future lies in the [[fediverse]].
But the same argument, I believe, applies to bridges: they increase the value of networks.
