That is not entirely correct - Pollock and most of the other Abstract expressionists , went through a serious surrealist phase before they broke off into the works they are famous for.

These guys some of you don't like but who are great artists none the less didn't just pop this stuff out of a polaroid (not at least till Warhol - another great and getting greater) - they spent lifetimes developing and studying very deeply the process and ideas of art.
That some here feel they can dismiss those efforts acknowledged by, most importantly other artists (you really don't qualify from what I see Snipe - sorry, but you're still ok) and serious minded people only reflects your lack of interest and curiosity and prejudice.
All of which great art exposes.

Serrano ? a flash in the pan- probably, but only time will tell.
Rockwell ? I like his stuff and agree illustration is both not generally art but that it can be art - some ads are amazing.
It is not all about US and what we LIKE.

Some folk don't like Shakespeare/Picasso but my guess people will be awestruck and still discussing them after we are all loooong gone.

Who knows, maybe Dipso will catch fire, quit his day job and live/work long enough to .... well no chance of that but still, nice try.
