One issue that I’ve been paying close attention to is the rise of the ‘portable social graph‘, which I’ll define as the ability to extract metadata about who you connect with online – both listing your ‘friends’ and contacts, and potentially doing a traffic analysis on the communication within this network.
Combined with a ‘portable attention graph‘ which begins to map what you look at online and gather similar metadata about your individual behaviors, new technologies offer unparalleled opportunities to do useful (and highly valuable – very highly valuable) behavioral mapping and targeting.
Now these emerging tools have value to me as a web user, to be sure. They allow strong recommendation engines, targeted content (including advertising), and allow me to function better in an economy where attention is a scarce commodity.
