I’m also interested in how you plan to grow the user base for meaningful crowd-sourced data. Without accounts, I appreciate the zero-friction onboarding, but I wonder if you’ve considered any optional identity or “gamification” features to keep regular users engaged.
Either way, it’s great to see a PWA done simply with Go, HTMX, and Tailwind. As a coffee fan myself, I’ll definitely try RoastQuest—thanks for sharing and good luck refining the concept!
