Rank-My-Favs
Do you keep lists of your favorite things, such as movies, books, recipes, or music albums? You might keep list(s) that looks like this: Network (1976) Lone Star (1996) Devils (1971) The Seventh Seal (1957) ... Many more films_h But how do you rank these? You might be tempted to order them by preference, but this could quickly get overwhelming for long lists. A much easier method is to use pairwise comparisons, which shows you single head-to-head pairs, and has you choose which one you like best. After doing a small number of these matchups, Rank-My-Favs can confidently create a ranked list for you. Under the hood, Rank-My-Favs can sort by either the win-rate, or the more advanced Glicko rating system.
