The Attention Economy: An Overview - 0 views

  • Because of this information explosion, we no longer read - we skim. The news that used to last a day now lasts just a few hours, simply because we need to pay attention to the new news. So it is becoming increasingly difficult to juggle all the news sources and keep on top of things. Which brings us to the law of information, stated first by Herbert Simon: the rapid growth of information
  • causes scarcity of attention.
  • It is also a big problem for news sites, blogs, search engines and online retailers. Our scarcity of attention hurts their economics.
  • ...12 more annotations...
  • What is the likelihood that you leave if you see an irrelevant headline? High.
  • The idea behind the Attention Economy is to create a marketplace where consumers are happy, because if they are shown relevant information
  • For example news feeds illustrate the point well, since they ask for consumers attention in exchange for the opportunity to show him/her advertising. The Search engines are similar in that respect, because they show ads in exchange for helping users find answers online.
  • It is important to realize that the key ingredient in the attention game is relevancy.
  • So the question is: how do you show the user relevant content? This is a complex problem that can be partially addressed by recommendation engines.
  • Another key ingredient of the Attention Economy is privacy.
  • The challenge is not just to protect consumers information, the challenge is to put the user in control of her information.
  • AttentionTrust succeeded in defining a simple, elegant, yet encompassing set of principles that define the rules of the game, by outlining the basic consumer rights in the AttentionEconomy: Property: You own your attention and can store it wherever you wish. You have CONTROL. Mobility: You can securely move your attention wherever you want, whenever you want to. You have the ability to TRANSFER your attention. Economy: You can pay attention to whomever you wish and receive value in return. Your attention has WORTH. Transparency: You can see exactly how your attention is being used.
  • So these seemingly simple rules ensure that participants transact fairly and that businesses do not monopolize users information
  • Ideally, a body of standards and protocols should be the technological foundation of the Attention Economy. Since these are early days of the conversation about attention, such standards do not yet exist. Here is an outline of what the Attention Architecture will look like (there is a detailed post on the topic from last year on my personal blog):
  • So from a technical point of view, the key to facilitating the attention marketplace is in decoupling of attention capturing, attention storage and attention recording services.
  • Silos: User information needs to be freed from proprietary silos Round Table: The industry needs to create a round table, to enable organizations to govern both the business and technical aspects of the attention economy (think Java Community Process). Education: People need to be educated about the value of their attention and the principles of attention economy. Avoiding privacy concerns will not work, instead they need to be tackled head on.

  • Economic sociologist Mark Granovetter
  • The Strength of Weak Ties
  • 1973 paper
  • people are more likely to acquire jobs that they learned about through individuals they interact with infrequently rather than their close personal
  • We are connected to core groups of strong ties that we interact with frequently and weak ties that we interact with infrequently

      Moreno (1951:1931)
  • the "strength of weak ties" states that weak ties facilitate information flow from disparate clusters of people

      Innovation related to distant people (weak connections)
  • tight-knit social circles tend to be small relative to people's entire social network, and when it comes to information about future job opportunities, it can be hard to find new leads.
  • Weak ties help spread novel information by bridging the gap between clusters of strong tie contacts
  • homophily [3], the tendency of individuals with similar characteristics to associate with one another.

      Inbreeding (Endogamia)
  • Individuals are connected to each other through workplaces, professions, schools, clubs, hobbies, political beliefs and other affiliations.  The homophily principle holds true for any kind of social network you can think of:
  • even the people you ride the bus with.
  • these commonalities not only shape how often people interact and what they talk about, but also what kinds of information they as individuals seek on the Web.
  • Homophily suggests that people who interact frequently are similar and may consume more of the same information. 
  • Individuals that interact less often tend to be dissimilar and may consume more diverse information. 
  • We found that people are more likely to share the information they were exposed to by their strong ties than by their weak ties on Facebook (Figure 3).   
  • strength between two individuals is measured by the number of comments a person received from their friend on Facebook
  • Other measurements of tie strength, like the number of messages, co-appearances in photos, and discussion on posts are discussed in our paper [5].
  • There are many possible explanations for the increased flow of information across strong ties
  • information shared by a person's weak ties is unlikely to be shared at a later point in time independently of those friends.
  • seeing content from a weak tie leads to a nearly tenfold increase in the likelihood that a person will share a link
  • In contrast, seeing information shared by a strong tie in News Feed makes people just six times as likely to share.
  • weak ties have the greatest potential to expose their friends to information that they would not have otherwise discovered.
  • though a person is more likely to share a single piece of information from one of their close contacts,
  • weak ties are collectively responsible for the majority of information spread. 
  • example (illustrated in Figure 5). Let's say a person has 100 contacts that are weak tie friends, and 10 that are strong tie friends.  Suppose the chance that you'll share something is very high for strong tie friends, say 50%
  • but the weak tie
  • sharing is only 15%
  • Therefore the amount of information spread due to weak and strong ties would be 100*0.15 = 15, and 10*0.50 = 5 respectively
  • so in total, people would end up sharing more from their weak tie friends.
  • because of their abundance, weak ties are primarily responsible for the majority of information spread on Facebook.
  • majority of people’s contacts are weak tie friends
  • We are exposed to and spread more information from our distant contacts than our close friends.
  • Since these distant contacts tend to be different from us, the bulk of information we consume and share comes from people with different perspectives
  • Our work
  • shows that online social networks can serve as an important medium for sharing new perspectives, products and world events.
  • very often, information does not "cascade" very far along the network.  This phenomenon has been observed in earlier research on Twitter in Everyone's an Influencer: Quantifying Influence on Twitter
  • and has been studied across other networks
  • by Sharad Goel and Duncan Watts at Yahoo! Research, NY.
  • person who click 'like' is in the weak ties group, and then who write a reply is in the strong ties group ?
  • share opinion , please

      Not necesarily but it's a good idea to assess FB behaviour.
