  • This, of course, relies on the fact that people's interests, preferences, and ideologies don't change too drastically over time.
  • A filtering system with preference-based recommendations, in essence, is the future of the social web.
  • The best implementations of a Collaborative Filtering (CF) system along with a preference based recommendation/discovery system that I have seen are always on music streaming and discovery sites.

  • As you can see from above, it is certainly possible to have a good collaborative filtering system without a recommendation engine
  • Collaborative Filtering (Wikipedia definition) is a mechanism used to filter large amounts of information by spreading the process of filtering among a large group of people.
  • The important thing, one that not many social sites realize, is that a (CF) system that doesn't automatically match content to your preferences, is inherently flawed. The reason for this is simple: Unless you can achieve perfect diversity and independence of opinion, one point of view will always dominate another on a particular platform. The dominant point of view on the social web is a left-leaning one, and without the ability to get the most appropriate pieces of content to the people that care most about them, the right-wing point of view gets buried almost every time.

    Anita Elberse, a Harvard Business School associate professor, has a really interesting article in the new Harvard Business Review that analyzes some Long Tail data and challenges some of the theory's predictions.

  • We don't want to argue that noise is always good, it's clearly important to spend some time without it every day.
  • Filtering isn't everything it's cracked up to be, though, and you wouldn't want to live in a fully filtered world all the time. Social media noise is an essential part of learning and living on the web.
  • It's one thing to find something you didn't know you needed right now, it's a whole other skill to be able to recall information that seemed marginally useful at best in the past at a time in the future when the need for it arises. Who can't remember doing that before? The ability to recall passively collected information that was gathered purposelessly in the past and put it to use in the future is a particularly powerful form of intelligence

  • Some people call it "serendipity," others call it "passive and opportunistic information acquisition." (Erdelez, see below.) The less limited the boundaries of your scope of view are, the more likely you may be to find things you didn't even think to look for.
  • Some people worry that being exposed to too much information will lead to not remembering very much of it. Scientists say that's not necessarily the case, though.
  • Quiet time, time off-line, deep thoughts and long books are all beautiful things - essential to a healthy intellectual, psychological and social life. We argue, though, that the opposite of all those things - online social media noise, is also a great opportunity that deserves to have its worth recognized at a time in history when many of us are struggling to deal with it.
  • Serendipitous search in the offline world is believed to be one of the ways our understanding of the world expands.
  • it's an interesting understanding of the way that swimming through noise helps us become who we are.

      !?
  • Erdelez argues that when prompted about a particular incident of accidental discovery our memories are better than we might think.
  • I think what makes noise unbearable is the guilty feeling we have to not read everything. But if we takes some times to dive in the noise, without feeling guilty of what we have missed, it is just a positive habit.
