SEOmoz pro just finished crawling my website and it's coming up with 250 rel canonical warnings.
Here's one example:
"
<dt>Description</dt>
<dt>Using rel=canonical suggests to search engines which URL should be seen as canonical."</dt>
<dt>That's all it's saying. I also have metarobots set to noodp,noydir - but I'm sure that doesn't make any difference with this.</dt>
