The profit of a good conversation is something learned and betterment initiated.
One of the attributes of a successful person, is that he is able to turn away from "vain talk" That is, conversations that are idle - and brings no benefit whatsoever. Worse if the conversation brings harm to ourselves or to others (as in backbiting or spreading rumours).
I want to say more - but I think you can figure out for yourselves what constitutes a good conversation and what is not.
