Comparing Your Lists to Someone Else's

Sometimes someone wants a suggestion for a drama they've never seen. Other times, you want to see how compatible a friendship might be based on shows someone has watched and how they rated them.

 Whatever the reason, it would be nice to be able to have ability to compare one's list versus your own. (Something similar to the way the website Goodreads does with books). Just an idea :)

P.S. IF this is already an ability of the site and I don't know how to do it, let me know!
