@Gargron imo something more akin to backlinks https://help.obsidian.md/How+to/Working+with+backlinks would be more powerful.
- they allow posts to reference more than 1 post, not just one.
- backlinks that haven’t been approved by the orig author or from blocked users don’t show up in a post
- unlike “quote posts” they don’t require users to learn a new concept for the compose UI, they just paste links to other posts as they normally would do when they want to reference them.
