are you thinking of AP enabling a static blog, or what’s the use case you have in mind?
It doesn't have to be a blog.
It could be something more like a classic websites or wikis people users to have.
...
One use-case is that —
I write something on a Retejo site.
If someone takes the URL to that, and, for example, puts it in the search-box of Mastodon — it will show up as Fediverse content.
I.e., that article I wrote and published on my Retejo site is a first-class object on the Fediverse and social-web.
It can even be boosted, etc.
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/reiver/statuses/115204357332168397 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
