Highly skewed power law distributions occur  all over the place. In science
journals it is the Brandford distribution
http://en.wikipedia.org/wiki/Bradford%27s_law. A similar patter occurs in
loans in a library which is most extreme in research libraries. The bulk of
loans are for high use course related titles while two thirds of the
collection might never be borrowed over a period of decades
