Attention is a currency. Right now Facebook, Google and co are making fortunes by converting our attention to cash through advertising. All we get in exchange is being tolerated on their properties as long as we are willing to be fed crappy adverts. We're not even consumers, we're like serfs of the medieval ages.
As it stands, both merchants (ad-buyers) and peasants (consumers) are being screwed, and the nobility (Google, FB & co) takes it all.
The merchants buy ads with cash hoping it will translate to sales so they get their money back from peasants, but it's a perverse system where the merchant that spends the most in ads gets to push and sell its product - however crappy it is. If you can't pay enough cash to nobility, they make your life as a merchant very difficult. Peasants have it even worse as they end up giving both attention to ads for (mostly crappy) stuff *and* money to the merchants (of which a good chunks end up with the nobility). It's a vicious circle where both merchants and peasants are indentured to the nobility which has no incentive in figuring out a better way for everyone.
But what if we got payed for our attention? What if there was a marketplace where we could signal what we think has value for other people and get payed if we where right? Suddenly we would have a system where true value would be recognized and where people who helped point out that value (by giving it attention first) would be rewarded. This seems like a much better system for both merchants and peasants but, of course, not for the current nobility.
Maybe it's time for the revolt of the serfs...
