I think it would be cool to see a leaderboard for the most followers. (The same type of leaderboard that it currently used for highest posters) You may think ,"People are going to start begging people for followers all the time.." Well, begging on EMC is not allowed, and begging for follows could have the same punishment as begging. (Also, the suggestion box description needs an update, since it is not really used for questions/concerns. Isn't that what the Empire Help & Support is for?)
Nah, I think the highest posters is enough. Honestly, these things don't make most people happier. For me, they'd mean I'd follow people, ask for follow back, and unfollow again a week later. Doesn't really seem social. One shouldn't need a leaderboard to be kind.
It would be cool seeing that kind of stuff but as 607 said, it would just be another 'competition'. A competition that will more than likely not be in good faith.
