I even like Clay when I half-agree with him, such as where he disagrees with Jakob Nielsen. Anyway, keep an ear out for the dude. He's one of the Good Ones. So are lots of other things, of course. Marriages, for example.
Metaphors are like that.
You borrow the meaning of one subject to make sense of another. By metaphorical implication, markets are also battlefields , environments , animals and sports arenas . I like conversation as a metaphor for markets because conversations tend to be positive-sum. I think my co-authors agree, though you'll probably get different explanations out of each of us. We didnt' say business is a conversation .
