Well, the deal about Clare Booth Luce, more than just her aesthetic appearance, was that in person, she was a witty, charming conversationalist.
Which is probably why the dull, taciturn Henry Luce was first attracted to her; she could carry the "socializing" part of life for him, while he tended to business.
Our computer personas are usually different from our real-life personas; in real life, the DUmmie PUnidiot "William Pitt" would be the life of the party, as compared with me.
I think it goes back to that age-old dilemma, where one is absent something, and seeks someone who has that something.
Well, I must be the exception to the rule, because I'm really smart in person too. :)
