@sp6ina Hubzilla with Activitypub is cool. I found Hubzilla to a good alternative to FB. I wrote a blog on it long time ago:
But I guess Activitypub clients are flawed. Can't see posts published before following somebody from Mastodon/Pleroma. The problem is not probably with Hubzilla because it happened with Masto/Pleroma users too.
Hubzilla to Hubzilla, no issues whatsoever.
