After scrubbing all but my sex and birthday information from my Facebook account, I noticed something peculiar.
Without the social graph to rely upon, Facebook’s “People You May Know” feature is worthless.
I haven’t heard of any of the four people Facebook suggests I may know.
This set of Facebook recommendations could instead be called “People You May Not Know”
I then drilled down into my account further to see what Facebook’s “Find friends from different parts of your life” feature produced.
To my surprise, Facebook couldn’t predict a single person I knew without my signaling to them who I am or who I already know (my social graph).
The same however can not be said of you to the degree that you have already provided Facebook with your personal and previously private social data.
