Gregory's Server
Post from @rabble on why he's chosen to use #Nostr and not #ActivityPub and the #Fediverse. He makes some compelling points. Personally I am not too worried about the server admin parts of his argument (I have enough control, even if I don't control the server), but I agree that this isn't ideal:
"You can’t use a single fediverse identity with your profile and followers in Peertube, Mobilizon, WriteFreely, and Pixelfed. You need a totally separate account in each one."

Some fediverse software already has tools to link and aggregate your different fediverse identities together -- as well as provide nomadic identity and single sign-on between compatible instances, but that isn't the software you've chosen to use.
There's a specification/proposal called FEP-ef61 which brings some of these abilities to the wider fediverse over ActivityPub (we're currently using a couple of other open protocols to make these features available in the fediverse right now for those who simply can't live without it).
Anyway, a number of folks are working on this today. Across a number of different software platforms.
