@j12t @tchambers @tommi The ActivityPub network (Fediverse) is often compared to email. I know it's a dubious analogy, at best, but people don't typically pick email servers (or email service providers) based on "community". However, communities still form as an "overlay" social network through mailing lists, newsletters and so on. Why can't an "instance" simply be an ATA (Activity Transfer Agent) and clients be AUAs (Activity User Agents) with the ability for any AUA to work with any ATA?
