Autoblog Featured Image Doesn't Import

Featured image will not get imported and saved. It doesn't even get saved in the Media Library.

Here's a post at http://interactiveonline.com/guide-social-logins/ which did not import a featured image.

The original post is at http://sixrevisions.com/web-development/social-logins/

The RSS feed is at http://feeds2.feedburner.com/SixRevisions

I've tried both of the following settings and still no luck

- Use media:thumbnail tag of a feed item
- Find the first image within content of a feed item

Any ideas?
