Make folders: organized page
Imagine that you are a shop that sells shoes and you want to launch a offline store. But you want to know which city. It is possible to make a tag like: locate-store. But it would be better to have a folder where everybody can add a city. So that people can vote an tell why that city. This is just a example. Your page will then become much organized. Folders help to organise major topics or to differentiate categories.
