Whoa! Google Using Drupal's Breadcrumbs?

It would seem Google has rolled out a new indexing/display feature that finds breadcrumbs and displays them instead of URLs for certain search results. Drupal's already game, it seems, judging by numerous searches I've taken a glance at today:

Drupal's Breadcrumb-enabled Search Results

I guess since Drupal's built towards this kind of data heirarchy, Google quickly and easily indexes the breadcrumbs... any other sites/CMSs already in the index in this manner?

Also, I wonder what this will do in terms of eye tracking and such - the first time I noticed it, my eye went to the URL immediately - of course, that could just be due to the novelty of the thing.
