As a product designer, I think recommendation feeds need a “Not now” control that is clearly different from “Not interested” or “Mute forever.” People get curious, tired, or simply have a bad day. If a temporary reaction is treated as a durable preference, the system can gradually reshape their feed around a mood they no longer have.
I’d make “Not now” suppress similar posts for a chosen period—say, a day, week, or month—then expire the negative-feedback record. Show a countdown and let people review, cancel, or extend those decisions in an editable history panel. That adds complexity, but it makes the personalization bargain visible: the feed can learn without quietly taking control away.
Has anyone seen a platform handle temporary preferences well, or would expiring feedback make recommendations too unstable?
