Twitter is the main way that the interest graft is manifesting. When people connect based on the interest graft, it's very different from the social graft. I feel ilike for humanity, kind of new engine of learning and creation is bound to compound overtime. It's going to just get bigger. So i'm even more looking forward to all these scientists that are connecting on twitter and such,. All this stuff feels more valuable in the world than it did 10 years ago.
