1. My saved items live in 100+ different silos. If they all lived in one place, say some kind of self-hosted personal data store, I probably would be less concerned. I've started to consolidate as much as I could into a handful of ecosystems (e.g., Pocket -> Keep, Dropbox -> Drive, Airtable -> Sheets, Todoist -> Tasks, RSS -> Gmail digest, Zoom -> Meet) and it seems to help a bit.
2. There is no easy way to organize, sort, prioritize, schedule, or even search for these items. Related items should be clustered together. Large items should be summarized and/or broken down. Urgent items should reach my inbox, be prioritized and scheduled. Popular and highly-rated items should rise to the top. Saved items should appear at the top of my Google search results. Without that, they might as well not exist.
