Field notes
The visible index mixes familiar pairings such as Duolingo × geography and LinkedIn × trades with broader combinations like Chipotle × Sweetgreen. Its methodology section says it checks for live, dead, or funded attempts and scores from counted signals; the extracted text does not show the underlying score calculations for each listing.
