You can put me down in the meaningless distinction camp. Back in the day, it was a useful designation to separate "American" board games like Sorry, Monopoly, Scrabble, and etc from "European" board games like Catan, Ticket to Ride, Carcassonne, and etc. As a whole, though, the hobby has moved on. Today, it's more useful to define games in terms of specific mechanics and level of interactivity, with similar games being grouped in genres. A few examples would be trick takers, deck builders, worker placement, auction games, and cube rails, though there are many more.
