To us, the Web is a sort of shared external memory. We do not have to remember unnecessary details: dates, sums, formulas, clauses, street names, detailed definitions. It is enough for us to have an abstract, the essence that is needed to process the information and relate it to others. Should we need the details, we can look them up within seconds. Similarly, we do not have to be experts in everything, because we know where to find people who specialise in what we ourselves do not know, and whom we can trust. People who will share their expertise with us not for profit, but because of our shared belief that information exists in motion, that it wants to be free, that we all benefit from the exchange of information.
