So far the related posts seem pretty good for my site. There's a few glitches. Sometimes an image from the current article appears (eg. http://www.superguide.com.au/boost-your-superannuation/working-is-the-new-retirement). Sometimes it picks some that really aren't relevant.

What is great though is that you can now track in Google Analytics exactly how many page views happen from people clicking related posts because it adds '?relatedposts...' to the url. Just filter for it in the top pages report.
