Travel Plug Adapter Info Site

01 THE IDEA

A viewer pitched rebuilding whatplug.info — an outdated utility site that tells travelers which electrical plug adapters they need by destination. The UI is a decade old and ripe for a redesign. The appeal is purely utilitarian: clean, fast, mobile-friendly answer to a common travel question.

Greg's verdict is lukewarm: this is a 'utility of the internet, not a business of the internet.' Traffic would be limited and intent is informational rather than transactional, making affiliate monetization nearly impossible. He acknowledges the intrinsic value but flags it as Ultra Niche — too niche to sustain a real business.

03 THE VERDICT

Greg's own verdict here is correct: this is a utility, not a business. Informational intent, no natural affiliate angle, and extremely limited traffic ceiling make the revenue potential negligible. Build it as a passion project or open-source contribution, not a startup.
