What I would like most is if I can create one ActivityPub account and use it on every ActivityPub service. This for me would be a perfect solution, because then I could use any app using a single account.
This is exactly it, this is what it sounded like when doing research about the Fediverse online. So perhaps that is the thing, but one user said that they can connect to all of them from Friendica. That’s the thing, it’s just to follow them, not create new PF or PT or Kbin posts from say Mastodon or Friendica. Posts can be done on one’s chosen instance, but the following would be so much more streamlined if it could be done from one place. :-) :-)
Actually created an account on there a few days ago, so will try that, but wasn’t able to find a beehaw post when testing earlier…
