mostly it's knowing nobody's gonna judge the half finished ones, i've got way more unfinished notes than polished ones

Congrats Mike on launching Caldera. Hashing every garden note into a signed manifest is a thoughtful touch, since it gives a public note a verifiable author and date without needing an account. On your question about links between gardens: when I link to [[@handle/Their note]] and they later rewrite it, does my link follow the latest version or point to the hash I saw? I would want the option to pin it, the way a citation does.

Cool that Caldera turns my Obsidian vault into a living profile with linked notes, so years of thinking actually become something shareable.
