Abstract Expressionism

I think I like abstract expressionism. Out of a slide of art I only liked Hans Hoffman's, "Crepuscule (1960)". I was looking at a selection from :http://www.speedmuseum.org/contemporary_art.html. The only one I'd want on my wall is Hans. I am jumping ahead to just look at a few things without studying the periods first. I want to pick out things I like or prefer and then find out what the genre is. I don't think this is the best selection really.
