I'm also an archivist. I've created http://arquiva.me/ from scratch which is archiving tweets (and other sources) related to people in Portugal. That archive preserves history in open format that anyone in the next centuries can access.

As archivist, we both need to pick our sources manually at some point. Nostr is quite a good tool for archives, since its format is flexible (long term preservation) and can work even fully offline.
