Aside from vitality, which in part is achieved by recommending content that users already like, I think that we are not well equipped to handle our own views being consistently reinforced. I believe this locks us into world views that are closed off from debate and scrutiny, and unless we intentionally try to question our own beliefs we’ll just be fed the content we already like and the opinions we already agree with / have.

I think you make a very interesting point about the impact of vitality over the long term, and I would like to read some of your thoughts about where we are headed, what can be done about it and why. I haven’t heard of Marshall McLuhan before.
