We already have the "list of users by edits", for people who truly want to know who has the most edits.

Adding a publicized leaderboard would just encourage people to make crappy edits to rise in rank, which is something this wiki DOES NOT need. As it is, only about 2% of a normal day's edits are worthwhile.
