Tags are just about the easiest thing possible to implement, especially in Ruby on Rails. With great plugins out there like acts_as_taggable_on_steroids, getting tags setup is a breeze. We've actually been accepting tags since day on arcades, but you couldn't view a listing of all arcades tagged with a specific tag. Now all tags should be links that show a listing of arcades -- making one more way to find the arcade you're looking for, or discover a new one. For instance, if you're looking for all arcades that are at theme parks or arcades in movie theaters it's only a click away!
