No, on the contrary :=) A glib talker is one who speaks smoothly and fluently, perhaps even to the point of being insincere. A person may also give a "glib" answer, one which lacks substance. For example, "the record producer was so glib that the pop group signed the contract without even reading it". (speak smoothly) Or The politician was very glib about the goals he would achieve (lacking substance)

sometimes,they will, i think.
