I would love an ELO-based restaurant ranking system
Yelp reviews aren’t very useful. Everything is 3.5 - 4.5 stars. Tells me nothing. Same for Google Maps. The 0-5 scale just doesn’t get used properly because of social norms toward high ratings.
What would work much better is…
Restaurant reviews simply based on whether one restaurant is better than another. Instead of writing a review, it should ask you which of two similar restaurants is better. That’s all you need to construct an ELO ranking scale.
One subtlety that’s nice about this is that it allows the rating to fluctuate every day. Rather than showing a sticky average from 3,000 old reviews, on an ELO scale the rating always changes based on what’s happening recently. Great new chef? It should be reflected immediately.

@tangjeff0 I ran a ~6 week deep-dive into Medical Tourism in late 2019. I reviewed all the SOTA literature including @iglenncohen’s book. I ultimately couldn’t build conviction 1/x
@tangjeff0 There are four types of medical tourism: (1) cosmetic (2) dental (3) medication (4) major procedure (surgery).
My assessment was that only (1) has a sufficient TAM. All others are small aggregate markets with dubious viability to expand the market. 2/x
@tangjeff0 The popular argument, which is always seductive, is that markets 2-4 could be 10x or 100x the size as a matter of pure economics, but practical issues quickly get in the way. Many of the best candidates for medical tourism are less able to travel. Tons and tons of liability. 3/x
