They also suffer from the needle in the haystack problem that a lot of big-data companies run into where they have become obsessed with invading peoples privacy with the hopes that someday they can make sense of it. But there is the caveat, sometimes even when you get a large and diverse population, you don't get trends you get static. because everyone forms a group equilibrium perpetually invalidating one another's thought to the point where no one knows whats right; static. You are who you are and whether Facebook knows it or not doesn't change who you are and what you expose online. Data is how facebook stays in business, the really shocking part is that you just found out.
