I really hope @Bonfire succeeds in their vision for federated groups. This is so important for the fediverse and I can envision many use cases in my own life.

Sadly, I'm not in a financial position to support them right now, but I hope I will be sometime soon.

Why Community Matters: Groups as the Next Step for the Fediverse

Federated groups in Bonfire will be spaces where communities gather to organise, care, and coordinate across the fediverse. They'll live next to your personal feed, but each group having a specific purpose: a study circle, a lab team, an activist collective, a local mutual aid crew, a project team. Inside you’ll find posts, conversations, calendars, shared resources, and more. Crucially, groups will be portable and interoperable.
