TrueSkill is a Bayesian ranking algorithm developed by Microsoft Research and used in the Xbox matchmaking system.
TrueSkill maintains a belief on the skill of each player; every time a player plays a game, the system accordingly changes the perceived skill of the player and acquires more confidence about this perception.

It certainly is the best ranking algorithm nowadays, mostly because it cares about time factor. Would be awesome had this implemented inside Gioco Ranking Class.

Some interesting links about it:
