I think a style guide is a great idea.  There have been some  
discussions along these lines in the past.  I'd say just start a  
"wiki folder" on puredata.info in the /docs/ section and edit it up.   
Something like /docs/style-guide/ I think that the main page could  
lay out all of the possible realms of style, like dollar arguments,  
abstractions, subpatches, inlets/outlets, trigger, etc.  Then the  
next step people can create sub-pages that outline all of their  
styles.  Then ultimately, things would be organized into a single

Terrorism is not an enemy.  It cannot be defeated.  It's a tactic.   
It's about as sensible to say we declare war on night attacks and  
expect we're going to win that war.  We're not going to win the war
