I agree with Fred Oliveira's argument, there is something to be said about the massive stores of information that is currently unavailable to the person whose data it is. I want to expand the sentiment that there is something merely valuable about this information and the connections between it, otherwise, you may get the impression that its sole value is for something like, say, advertising (which it certainly is). I wish to contend that this dark data has greater sentimental, historical, and anthropological data for personal and future educational usages. This is a segment of sociological data that is largely unreachable, yet constitutes a huge portion of our lives. It therefore deserves to be accessible to all and not just search indexing algorithms.
