The wiki leaderboard was created prior to Update 2.0 which introduced the friends leaderboard. It virtually superseded the wiki leaderboard. Moreover, I had to update it manually and it soon became a case of me routinely copying stats of those who had friended me, with actual submissions becoming rare. It lasted for over a year before we pulled the plug on it, and certainly, it worked quite well during that time.

You're free to create your own leaderboard. However, I think you ought to just have everyone add their in-game usernames on a thread so people can add them as friends. I honestly do not recall that having ever been done before, and I imagine maintaining a leaderboard would soon get boring. Consider either.
