Actually I don't think there should be a distinction.

I envision a unified hierarchy. I.e. Cookbook.Foo.Talk is the text 
snippet inside the Cookbook.Foo hierarchy.
Whether it's just a part of the Cookbook.Foo page (i.e. a subpage, in my 
terminology), or whether it's a separate page located in the 
Cookbook.Foo group, that should be of little concern: URLs to that text 
snippet shouldn't have to change just because an author chose to switch 
from one configuration to the other.

Hope this clarifies my ideas a bit.


Um, speaking of clarification, terminology seems a bit unclear (and even 
partially misleading). Let me try to give intuitive names to all the 
entities that I have seen floating around:

Group: a bunch of related pages.
Subgroup [new]: a group inside a group.

Group page: the page that represents the group in some way (e.g. a 
summary page). Group page naming is one of the problems that started 
this discussion.

Section [new]: a part of a page; possibly separately editable; possibly 
Subsection [new]: a part of a section.
convertible into a subpage and vice versa.

Subpage [changed]: a page in a group (i.e. "x is a subpage of group y"; 
sloppy usage would be "x is a subpage of page p", where p is the group 
page of some group y).


What does everybody think?
