Consider this: I can go to Antarctica and get cash from an ATM without a glitch but should I fall ill during my travels a hospital there could not access my medical records or know what medications I am on.
Artistic qualities that once seemed undeniable don't seem so now. Sometimes these fluctuations are only fickleness of taste momentary glitches in an artist's work or an artist getting ahead of his audience (it took me ten years to catch up to Albert Oehlen). Other times however these problems mean there's something wrong with the art.
The reason why you know more funny dudes than funny chicks is that dudes are funnier than chicks. If my daughter has a mediocre sense of humor I'm just gonna tell her 'Be a staff writer for a sitcom. Because they'll have to hire you they can't really fire you and you don't have to produce that much. It'll be awesome.'
