Sets are great for tagging or tracking any other properties of a value for which duplicates don't make any sense (or where we want to apply set operations such as intersections and unions).
Of course, lists aren't only good for storing references to other keys. The values can be anything. You could use lists to store logs or track the path a user is taking through a site. If you were building a game, you might use it to track a queued user actions.
