A Portrait of Ignorance, Simply Drawn

There's this thread currently stemming from Mike San Giacomo's latest treading into the realms of blissful ignorance in regards to "realistic" and "simple" artwork. As you'll note in thread, I myself have a few things to say, which is odd since I rarely actually take part -- or read -- most of Newsarama. What's more interesting is Alan David Doane's response, Journey into Ignorance.
