Hell, just the server logs (timestamps, IP addresses and exact URLs) would be unbelievably valuable.
People say that, but the actual data would be so vast and with so little actual usability, that the dilution of it still results in largely garbage data. Its only when you have a particular focus and have the ability to filter to that focus that the data becomes very valuable.
Even banks and card processors, who have direct, legal, and completely open access to data as critical as where every one of their customers spends money struggle to do more than harvest aggregated usage patterns. The idea that data volumes, at a couple more orders of magnitude and notably more generalized will be easily processed and harvested ends up being pretty silly.
