Except from Gary Kilmer:
What is the primary way we human beings communicate our needs, experiences, preferences, hopes, fears, problems and solutions? It is through conversation — talking with each other. All of the modern technical marvels (email, tweets, blogs and all their kin) only facilitate that conversation. They do not replace it.
In this blog post I will relate my own experiences in using “the conversation” as a development tool in field projects in several countries.
