The first ever crowd sourced TED talk - you can read and edit this TED 2012 talk

As some of you know, I'm going to give a talk at TED 2012.
My idea is about using crowd wisdom in social networks to think together with others.

Over the last few weeks I have built the presentation with your help (here's a link to a conversation where it all started - )

My talk contains examples, sentences and even jokes I got through the wisdom of the crowds, your wisdom.

Now I am proud to present the first and full draft of the text as a Wiki page in Wikipedia:

You are welcome to edit it as you wish. Fix mistakes, add, erase and/or anything that can make the presentation better.

I'll be also very happy to get your feedback in this conversation.


  • Jan 7 2012: I joined your marvellous idea, see at wikipedia!

    Jan 4 2012: For some reason the reply button isn't working so I'll answer with another post. I think the idea of crowdsourcing a talk is great, but you of course lose the element of surprise if you lay all your cards on the table.

    I would remove the part announcing that a real bull will enter. Furthermore, I would maybe keep one more thing secret so it will surprise those who read and contributed to the talk and are sure they know what to expect.

    I don't know how much of the TED audience will view the talk prior to the conference but I'd keep some aces up my sleeve (to keep up the cards' metaphors :D)
  • Jan 7 2012: I contributed at the wikipedia site an idea worth spreading, but it obviously was deleted. It is a stunning blueprint for Palestine, initiated by the American thinktank Rand Corporation in 2002. You should be able to still read it on the log, under freedplanet. And on the website of
  • Jan 5 2012: BTW - did you consider how and when you'll get Teddy OFF the stage :-)...?
    You don't want him getting all the attention as you go on speaking.

      Jan 8 2012: Amir, the bull should be on stage for less and 1 minute. It's just at the beginning as I demonstrate what is crowd wisdom...
  • Jan 5 2012: Great way to go Lior!
    Indeed - you walk the talk...
    I added my small contribution to the Wiki.
    Good luck - I am sure you'll do great.

    Jan 5 2012: Great idea for the Teddy aka the bull i would advice you bring it live on the stage as planned because its a sticky factor especially in presentations you need something to break the pattern and that is a good one.
  • Jan 5 2012: Great Idea, I've just added some bits to the talk Wiki page. I added my name to the "Edit Summary", is that correct?

    I did my Honors Degree final year project dissertation on this subject. You can read the proposal here: Positive Network Effects - Benefits of Web 2.0

    I could send you the complete dissertation if you like but it's pretty big. It concluded that there needs to be proper systems in place to incentivize participation and maintain a balance of expertise and opinion in the group.

    Avoiding forced consensus through peer pressure and mob like behavior (which can arise from anonymity) and encouraging input from a range of opinions (avoiding the "X country's Got Talent" negative effect from using a narrow section of public - young girls in that case).

    Best of luck and I hope you like my additions to your speech, I look forward to seeing it as a TED video!
  • Jan 5 2012: Great topic choice. After all, neural networks, healthy development, and reduction of stress has a direct correlation with social contact.

    Jan 4 2012: Good job, Lior!

    Unfortunately, it will no longer be a surprise when you bring the bull on stage. Maybe TEDsters will look up how much a bull weighs before the talk :D By the way, do you have a back-up plan in case the answers differ too much?

      Jan 4 2012: Hi Sabin,
      Do you think I should delete this part from the text so that people will be surprised?....
      I do have a backup plan and I'll probably start collecting estimates 24 hours before my talk.

          Jan 4 2012: I'm going to do a test in a few weeks before the event with another bull. I'll shoot an hd video and ask my social network friends for its weight.... I hope it works out :-)
      • Jan 4 2012: I think it will reach way more than those who contributed so the element of suprise is still there

        Jan 4 2012: Compliments on the idea Lior. With regard to the bull...leave it in the text. I would be very interested to see how all the crowd sourced efforts worked out whether if I were to be a participant at TED 2012 or see it later in the video. And then there's also the fact that many may not even know about it yet.
        Good luck on the Talk.
