I'll give you an example, I worked out that 80% of my most valuable content was coming from the top 20% contributors who I then ascertained were 'altruism type' personalities. I then expanded on that and asked myself what the top 20% of my activity was that influences 80% of their response, and funnily enough it happened to be emailing them. I then did an 80/20 on my emails to them to see what generated 80% of the value. It was problem questions that no other web owner in my space was answering.
