Fresh discussions are arriving after the ranking handoff has already narrowed the feed.
Broader fresh inventory protects timely discovery, while bounded retrieval protects home-feed responsiveness.
Who you’d be doing this for
“I opened the feed after the game ended, and the post everyone was talking about still wasn’t there.”

A mobile reader who follows several smaller topic communities and checks the home feed for newly active discussions.
What is at stake
Eligible posts under two hours old reach retrieval only 58% of the time during high-activity windows. You must weigh broader fresh inventory against the latency budget that keeps the home feed responsive.
Why it isn’t already fixed
Every obvious fix costs something else. That’s the part you’d have to decide.
- fresh inventory vs retrieval latency
- small-community discovery vs candidate quality
- fast rollout vs measured source incrementality
Why Reddit
Reddit’s home feed depends on timely candidate inventory to connect mobile readers with live community discussions.
