I don’t necessarily think it’s a bad thing to have some platforms be specialized around really particular kinds of activities, but I have like 7 different accounts floating around. It’s tiring. I’d really just prefer a good generalist platform and a handful of different apps that all hook into the same account.
That being said, I don’t mind the concept of following someone’s Pixelfed to see their neat photography pics, or another person’s PeerTube to watch their videos. In fact, if my hypothetical server can interoperate with them without any major issues, I’d consider that a win for me.
