Facebook may be on the social front...but if you look at it from a different angle, the fact that data is being collected on all fronts, from search, email, video, social and DNS, Google is the single monopoly.
That's semantic creep. The grandparent post was about antitrust law. Antitrust interprets a "monopoly" in the market sense. It's true that you can attach other meanings to the word and gain new insights from interesting discussion, but that has no bearing on the ability of the DoJ to bring antitrust suits against google.
