Last week’s post showed how a relatively few number of volunteers do a huge number of classifications. By today, the top 0.3% of citizen scientists (the top ten) have done 31,528 classifications between them, which is a staggering 19% of all classifications. To my surprise, BashTheBug is exactly following the Pareto Principle which says that roughly 80% of events come from 20% of the causes. For BashTheBug after five weeks the top 20% of users (727) have done 82% of all classifications.
