Thanks again for your sharing and Guy Kawasaki’s recommending. I found it from http://www.openforum.com/idea-hub/topics/the-world/article/how-to-design-for-social-traction-guy-kawasaki-1.

Thank you for the great presentation!

Point 3 on “Levels of Description” is really interesting. I feel like this is something most web sites do, even if they do not know they are doing so. I’d love to see more illustrated examples of this in the wild, as you did with Netflix.

Under first time use, I saw an interesting example of a welcome box at http://launch.ly/ which included a Retweet button – a subtle social influence factor right in the opening message. This is also an example where first time use will normally happen before sign up. (Only thing I don’t like is their use of dotted underlines, which should indicate a link.)

After seeing the slides for “Sense of Efficacy” I was left wondering what are all the options available for moving your application around in the challenges/skills graph. I guess you’ll include even more examples later, perhaps even a list of ideas? It always amazes me how well video game designers ride the balance but how difficult it is to do in applications.
