Super is a bit magic, quite complicated, and some people don't like it 
(basically, super is mainly to be used in complex inheritance case with 
diamond shape hierarchies and such, to automate the method resolution 
order).

If you want to give a try at understanding "super", you should read 
Guido's `Unifying types and classes in Python 2.2`, chapters on MRO, 
super and cooperative methods 
(http://www.python.org/2.2.3/descrintro.html#mro) (nb: you may also read 
the rest of the document, it lists all the magic introduced in the 
language with 2.2).
