It's a different way to look up locations through the entire world, using three random words you can find any address or location with in 10 feet.
The only downside I see is the three words are all English words. Which could be unfamiliar to non English speaking parts of the world.
Just think about how easy it would be teach your children where they live by memorizing just three words instead of House number, Street name, City, State, Zip code.
