List Bulb 2.2: Weekly Launch Cohorts

List Bulb 2.0 gave founders accounts and plans. 2.1 was lifecycle polish — unlisting, emails, analytics — all on the changelog, no dedicated post. 2.2 (August 1, 2026) changes something more fundamental: how launches compete for attention.

The problem with one long feed

Before 2.2, every product landed in the same undifferentiated stream. A great product launched on a slow Tuesday could get buried under six months of accumulated listings by the time anyone scrolled past the homepage fold. Visibility depended on when you happened to launch relative to everything that came before you — not on your own launch week.

What changed

Weekly cohorts. Products now launch into a cohort tied to the calendar week (Monday–Sunday) they go live in, instead of competing against the entire catalog's history. Fresh visibility every Monday.

Launches hub. Browse any past or upcoming week's cohort from one place — see Launches. The week picker shows the date range and launch count for each week, with a live indicator on the current one.

Bulb-count ranking. Within a cohort, ranking is straightforward: most bulbs (upvotes) wins. The top spot in a concluded week gets a badge on its listing — shown only once the week is actually over, not while voting is still live.
