Show HN: An obsidian plugin inspired by the 'I deleted my second brain' article

https://versen.substack.com/p/to-learn-you-need-to-forget
2•boars_tiffs•10h ago
me and my friend built leaves, an obsidian plugin that automatically archives notes unless you actively tend to them (by editing or linking).

we thought of it after reading this article https://medium.com/westenberg/i-deleted-my-second-brain-b7a6.... most of our "second brain" content is just digital hoarding. notes without context or connections die after a set time, making space for what actually matters.

do you think artificial scarcity/decay could improve pkm systems? have you tried similar approaches to combat information overload in your own workflows?
