Alexandria is a "social network" for ideas. A way for ideas to connect and evolve.

1) It aims to be a knowledge commons/ecosystem on top of nostr. The intuition is that notes can link together. Like paragraphs in a chapter or chapters in a book, and so on.

2) Users can use it like a regular note taking app, or to publish these linked notes to form blogs, books, documentation etc.

3) Other users can take those notes, mix them into their own collection of ideas, like a collage.

Then when you put that infrastructure on nostr, with each relay having their own standards (from personal notes, to focused communities and disciplines, to general knowledge) - ideas propagate and combine across disciplines and communities.

On one hand, each community keeps their signal quality. On the other, the conversation doesn't have to stop at the community.
