As a matter of fact, they are nothing but no use talking. I have seen some people who talk very nicely and only on a subject they take and they can go to the depth of the subject. Such people talk only about what is relevant and what they know. It will be good to hear from such people.
But some people spend their time talking always some rubbish and useless. Such people should not be encouraged and by hearing their talks we are not going to gain any subject knowledge.
These people do not have a thorough knowledge of a particular field but they have some little knowledge of all the fields and you can say that they are actually generalist having no core strength.
In essence it is better to avoid these people and not call them for discussion because the net gain after the discussion will be nil. It will only be a wastage of time.
Knowledge is power.
But it is not correct according to me. Most of people are talking with others with a limit.
With some people only they are talking more where such persons are fond to their heart.
Some people are talking more to others when they expect something from others
Some people never talk to others and do talk only when they called by others.
Marketing people do talk more as they have to turn the customers to their side. By practice, they used to talk with others without time limit.

Even this challenging situation would ease
Those who talk less think more. And in many cases, being silent means that they are thinking in their minds. Even a less talkative person is interested in talking when everyone is talking in a discussion, but the main obstacle for him to start talking or saying something is that he listens to everyone and prefers to think. And it is this ability to think that makes intelligent people less talkative.
Those who are quieter and prefer to talk less read and write more. They want to spend all their energy on something constructive. They also like to work creatively. And in this their intellect becomes sharp. This issue is rarely noticed among those who talk more.
