Also, as far as listing contemporary artists, I think the shorter the list the better.  A fair listing would be exhaustive, overwhelming and completely unnecessary.  Readers simply need to be directed to the "contemporary artists" page.  There are a few exemplary artists that should be included in the article, like Robert Smithson.  But discussion should focus on specific ideas or approaches these artists introduced that developed contemporary art in general. 

 I would like to take this challenge on!  It may take me a few weeks to get it organized and improved, but I don't think it's an impossible task.  I will need and will greatly appreciate your support and input as I tackle this mountain.  Thanks!
