Very nice. I heartily agree that there needn't be a clear line drawn between digital and non-digital interactions. If anything, digital spaces have allowed us to create new types of interactions that serve specific purposes. We have a long history of designing non-digital spaces around specific types on interactions, and I don't see those that we have online as intrinsically limited or less genuine. In fact, as b_b mentions the ability to say something and let it stand creates new opportunities. Even text messaging brings the ability to engage a conversation with someone without first greeting them, or asking them how their day is going. If anything, our world of social interactions is becoming enriched. Of course there will be misadventures with new modes and technologies, but in the end, the most fulfilling platforms will prevail.
