Developer jonathanwilke welcomed a new sponsor, Chrome Goldmine—a paid dataset for indie makers listing 9,656 expired Chrome extensions (killed by Manifest V3 or abandonment), each with historical users, category, rebuild difficulty, cause of death, current competitors, and a step-by-step rebuild plan.

Priced at a one-time $23.20, the pitch is "demand already proven, just rebuild it"—sample entries include Tab Suspender Reloaded (91,400 historical users). Used by 45+ indie makers, it's a clean one-person-business case of packaging research into a dataset and selling it.
