The best thing in the world that can happen, is that Facebook (and others) steal market share away from Google. This will force more competition, which will be good for the industry at large. It is never good to have a monopoly in any industry; having one creates complacency and lethargy from the kingpin, which we have all seen in recent years. This is all good news for everyone, IMO.
