The community part is something that’s still being worked on. We get through it by having something akin to planets that people can follow (try subscribing to https://stream.indieweb.org/ for example! check out https://indieweb.xyz!) but there’s definitely more that can be done. What kind of ideas do you have in mind?

I personally want to work towards having me define my community on my site (internally, of course) and let my tooling for subscribing to people adapt that and grow from there. That way, my site is always the authority to who and what I want to engage with.
