Hi Jeff,

I recently published my related content plugin here https://wordpress.org/plugins/sebar/. It has a lot of cool feature like:

1. Mobile responsive with support swipe and mouse drag
2. Browse YouTube videos from plugin dashboard
3. Integration with Google Feed Finder
4. Display related contents from internal WP Post based on (individual post/page, tag, category, author and custom query)
5. Analytics
6. Custom landing page
7. Widget
8. More

Hopefully it can help someone out there.
