Style question: 'return None' vs 'pass' in do-nothing methods?

[Elf M. Sternberg]

	I'm using Webware for a project and noticed that in version 0.6 
Chuck finally included support for cascading style sheets.  I had put my 
own support into the project I was working on, and I notice that there 
seems to be a stylistic difference between what he did and what I did.  
For pages that don't need it (such as redirects), I defined it as:

def stylesheet(self):
	return None

Whereas Webware used:

def writeStyleSheet(self):
	pass

	Is there a reason for favoring one over the other?

I have seen the light.  I was not impressed.
