In addition to showing reputation scores, SO should rank users. In the users section, users are ordered by the reputations they have.

Each user should also have a unique rank, since many users can have the same reputation score.

Rank must follow the order laid out by reputation, but for those having similar reputation, an additional formula should be defined which can rank users based on tags, time since registration, frequency of activity and/or helpfulness of their answers.
