seriously though, i have struggled with tab/bookmark hoarding, it's a huge relief when you recognize it for what it is and quit. IME the bigger/dustier the backlog gets the more vague psychological guilt accumulates, a weight which isn't truly recognized until it's gone.
Or maybe we just need to learn how to prioritize better? Or do some kind of stagewise workflow where the superficial ingestion/collection is followed by multiple steps of culling the less relevant stuff (but still without real deletion, just in case for later). Or perhaps we could now write a sentence of why we think the link may be relevant and what future event or future state of some project or development might make this link gain in relevance again? And then again we could declare that this has happened and what are now the links that are relevant?
I could see some LLM product in this space, but I think this market is fairly niche.
