People can be different parts of these three classifications to different groups.
I would add also that one entity (human) can be different roles on different days; at different times; on different topics; or over time.
Also suggestion adjust the numbers (as they were made up) to the pareto principle
The Pareto Principle is probably the proportion of lurkers to participants; the number should really be 96-4, but 95-5 is a nice, round number, and has a certain… statistical flavor.
