Opt-in Intelligent Discoverability

This idea is based on Facebook intelligently matching across patterns and trends in the data you upload to the site. If you two independent users, anonymous to each other, have a high-degree of corresponding "likes" then Facebook should suggest a friend match. Such a process would help Facebook further integrate ties between different groups of friends, making it increasingly relevant. The only suggestion tool now is "People you may know" through one or more mutual friends, but with networks, likes, locations, check-ins and keywords at its disposal, I wonder if Facebook could rapidly expand in this area. It could really take the current service (a reflection of realworld life) and turn it into a whole new life of its own. Of course the privacy critics won't like this one, so I expect such a service to be opt-in thenagain people have willingly provided such information in the past.
