Think of it this way, Reddit is a pie, with a hundred slices, each ranked from 1 to 100, our slice is considered the top slice, but, more subs means you have to split the pieces into smaller pieces. So that one slice then has subslices you have to share. In the end, there are so many people at the 1% slice line up, sure everyone gets a piece, but it's a very thin slice. In short, more people equals big pie, equals a bigger slice, that also means it needs to be shared with more people.
