2 of the above posters present a stark contrast
one is a sarcastic remark, a bad joke, from one who is controlled by the ego, an ego that says, "look at me, love me, kiss me, pay attention to me".
this is gamma male behaviour.
and the other poster, 2 posts, is a summation of important points pertaining to the subject matter at hand, providing a handy, neat summary of another post.
this is maybe like a hard working delta or sigma male.
