All the RSS and Atom files seem to attempt to present the same 
data in slightly different dialects of the same language.

This nicely exposes some of the key issues in 
XML data interchange:

1) using XML simplifies token parsing, but doesn't help much 
   when processing grammars. As for being able to convey message
   semantics ... 

2) MovableType now includes 4 different templates for syndication: 
   is Stove-piping really the best way to version XML languages :-(

3) something which is quintessentially pub-sub ends up using 
   polling.

OTOH the massive success of RSS does demonstrate that simple
approaches often work best. 'Good-enough' has been the story
of the Web.
