How? You had to spread it around and, far as I'm aware, neg rep was a small percentage of the total rep handed out.
I can tell you from personal experience that the way a poster would accumulate a high rep score was from an extremely broad swath of people liking your posts.
The one change I think the system needed was that everybody's vote should have counted the same. I know that when my vote power got fairly high I made a conscious decision not to rep other posters with high rep scores all that often (essentially reserving it for their platinum-level posts). I thought it was important to recognize less frequent and new posters when they posted something really good, not to mention that's how you grow a community. Though I never discussed it with anyone else, it seemed that other posters in the same boat as me did the same.
