Some kind of discovery protocol for blogs RSS feeds would be nice. Maybe BlueSky will fill that void. There probably are services already doing something like that, but it still puts a central authority in control of the discovery.
Yeah … RSS will likely play a huge role and for mass adoption or a large number of eyes it’ll need to be a centralized thing but then you get all the problems of centralization including the ability to say what can and can’t be part of the new discoverability index.
