I've been using the Internet since 1992-3. Lately I'm feeling more and more like these 7% have the right idea.
I don't think you can generalize the internet to be bad. That's like saying processed food is bad: Yes, we would not have the obesity problems we have now without them, but neither would we have been able to build our civilization as is or be able to be as well nourished as we are. The direction the net is currently going looks a bit worrying, I definitely agree. But I would not want to miss all the awesome advantage…
I am optimistic that the best social media sites have yet to be designed--rather than optimizing to squeeze the most engagement, ad dollars, or whatever, I like to imagine algorithms that seek to encourage pro-social behavior, friendliness, happiness, fun, healthy habits. We may discover that Twitter and Facebook are fundamentally incapable of doing these things as well as their future replacement, whatever that may be.
