**I think it's best that I stay out of any conversation regarding who is and isn't notable - my position on notability here would probably be extremely biased, and my concern about this article is that it's one pissed off blogger away from becoming a clusterfuck or home to a revert war.  I agree with you that most of the folks are certainly notable, but this article shouldn't become a list.  The purpose of this article should be to adequately explain what art blogs are, how they relate to traditional art media and any other issues that are specific to art blogs, relative to non-art blogs.  Perhaps any major events that have shaped the art blog community should be mentioned, such as the Peter Plagens article, which is already present.  Maybe a better idea would be to create a second article that lists arts bloggers - right now this article looks like a list, and if external links are added back in, it basically becomes a link farm, which is not helpful to anyone.
