I don't expect platforms like Pairagraph and Letter to change the world over night. But I really do believe that they could have a profound impact. As Carter and I have said in the past, our dream is to live in a society where it is commonplace for people who disagree to make genuine efforts to have conversations with one another. Our goal with Pairagraph is to create a place on the web that facilitates this.
If we get there, it will be inch by inch.
