I have my modern art history mid term tonight.

Does it really matter that I know by heart Harold Rosenberg's theory on abstract expressionism - action painting?

Does anyone still care about Harold Rosenberg's abstract expressionism - colour field theory, or any of the art that came out of this movement?

Will I get extra points at a cocktail party because I can tell you the similarities and differences between Ab-Ex Action and Ab-Ex Colour Field?

What about extra points for knowing the differences and similarities between Ab-Ex New York and Art Informel in Europe?
