We now have web in our pockets, as part of our smart phones, and it is always turned on. We share, or at least have the easy ability to share, all aspects of our lives. The trick is to navigate all this information effectively. Share critical info such as what merchants to trust, where to obtain food, what animals to eat, where to get supplies and which service providers to go to.
Humans were always social. Now it is "Social Instant", and as always, our friends will be one of the largest influences on our purchase decisions and behaviour.
