Is there any rhyme or reason to Google supps?

Have you had any canonical issues with WP serving up pages in both forms:

domain.com/page/
and
domain.com/page

?

Nope..I never had problems with that. I never even seen my blog link to pages without the final /.

If your blog does that though, you want to fix it. Google treats those as two distinct urls.
