Maybe they haven't been as active as you are or provided as good quality comments or advice than you have.

Not that many people have left (as in been removed from the system).

lol, maybe its because your giving good advice. Your lucky im going down lol.

As you participate in the world of Minti, be it writing a comment here and there, or voting on comments etc, you get rewarded by moving up the ranks. Also not long ago the Minti powers that be amended the way the rankings were working and as a result there was a big jump for some people in the rankings. Have a look at some of the links I have put in above to give you more of an outlook on how things work. Leisa

Not sure how people move up the ranks but I think if you leave comments on other peoples blogs or you give good advice which gets good votes I think this all helps.
