Conversation matters to any community of interest (including our community of a single mind), but nowhere is the value of conversation more clear than in commerce, because commerce cannot flourish, or even exist, without conversation. Conversation is internal and external and the skill to design and implement conversations that enhance relationship/meaning and understanding is the fabric of interpersonal and commercial communication infrastructure. In simple terms conversation is to open a channel, commit to engage, constructing meaning, evolving and transforming in the process, converging on an agreement and acting or transacting. Through conversation we learn, coordinate and collaborate on goals towards a common vision with awareness of the limits a conversation can have e.g. the conversational infrastructure and conversational participants involved.
