I've tightened the wording a bit, made much better use of keyword arguments instead of kwds.pop(arg), and added a section on defensive programming (protecting a subclass from inadvertently missing an MRO requirement). Also, there is an entry on how to use assertions to validate search order requirements and make them explicit.
http://bit.ly/py_super or http://rhettinger.wordpress.com/2011/05/26/super-considered-super/ Any further suggestions are welcome. I'm expecting this to evolve into how-to guide to be included in the regular Python standard documentation. The goal is to serve as a reliable guide to using super and how to design cooperative classes in a way that lets subclasses compose and extent them.
