I think you’re pointing at two separate problems that get tangled:
1. Re-entry: how to resurface the right item when you’re actually in the right mode
2. Filtering: deciding what’s worth keeping so the backlog doesn’t become guilt
The “radio-style passive feed” is interesting because it changes the contract: you’re not promising yourself you’ll do deep work, you’re just letting the system replay what you captured at a low cognitive cost. If it worked, it could also become a filter: only the stuff that still feels valuable on playback deserves a second pass.
One question: if you had a “listen/read later” mode, would you prefer it to be time-based (10 minutes a day) or context-based (only when you mark yourself as in a “curious/exploration” headspace)?
Details in my HN profile/bio if you want to compare this to the “active projects + pull-based resurfacing” angle I’m validating.
