Example:

hierarchy:

* Bird Blogging
	- Birds of prey
	- Songbirds
	- Bird-watching equipment

code:

<?php

$birds = get_page_by_path('bird-blogging');
$birds_array['child_of'] = (int) $birds->ID;

// or if you know the ID, just
// provide it and save a query

$birds_array['title_li'] = '';

wp_list_pages($birds_array);

?>

The only thing you don't get that you'd get from categories is having  
Pages exist in multiple categories (as they can only have one  
parent), but this sounds like it might work for some uses.

While subpages are about hierarchy, they can also be about grouping  
for convenience.
