My ratings:
Communities - 5/5 (tons are local, most others are federated)
Culture - 4/5 (nothing is perfect)
Moderation - 5/5 (seems reasonable, stays out of the way most of the time)
Availability - 5/5 (no issues for one year, beyond quick updates and such)
Performance - 5/5 (hosted in New Zealand but works well for me)
Federation - 5/5 (just a handful of servers are not federated and the list is public, can be reviewed)
Their home page tagline:
Federated, open‑source, ad‑free, and fully under your control. Build or join a community that reflects your values with no corporate overlords.
I moved to my piefed.social account last year when the lemm.ee instance I'd been on for 2 years prior shut down. Piefed, the lemmy-compatible software has lots of additional quality of life features, so that's great, and piedfed.social's admins stay mostly out of the way and just let us converse. There are about 700 daily users, from what they self-report and that to me is plenty of people to always find someone to chat with.
I mod a few communities on here, including !fullmoviesonyoutube@piefed.social , !raygungothic@piefed.social and !artporn@piefed.social.
I'd love to hear what others, both on and off piefed.social think of this instance.
Cheers,
