@strypey @bhaugen @KevinMarks @cwebber Not an expert but I don't think it's *necessarily* (although very common) about being self-hosted, it's about owning your identity and your data. e.g. https://micro.blog provides hosted services that adhere to indieweb protocols (and principles).
In some ways its closer to Hubzilla than Mastodon, IMO.
The reason I mention that (and hope I'm correct in saying so) is that I think it's vital that indieweb does not expect everyone will self-host.
