Tool for ranking your preferences, by doing pairwise comparisons (Elo algorithm)

This is an online tool I wrote that helps you to sort a list of items by importance. You paste in a list of items, then you are asked to compare them two at a time. As you go, it shows you an updated sorted list. It uses the Elo ranking algorithm, so that you still get decent results even if you don't do all pair combinations.<p>Why did I write this? My wife and I are thinking about moving and there are several dozen preferences we have, and I wanted to know which were our top 10 and in what order. You can use this for ranking any list of preferences: things you are looking for in a new car, favorite skills/interests to focus on when deciding on a new career, etc.
