@Cyracuz,
That's an interesting question Cyracuz, requiring some thought.
I enjoy reading and posting here on A2k, and am fond of the color of many of the other regular posters.
It's an odd relationship, one has with another, online. A reactive sort of relationship, we really have no knowledge of who is in the room, until they post.
There is no body language, no quiet observations, no humans being. We react solely to the product of each other's minds.
There are no prejudices toward appearance, physical intimidations or fears, no foul odors, nor annoying clickings of the teeth.
I don't believe we can know the whole character of a person without the physical element. We may know the intellect, but the human is not entirely a being of the intellect.
