Kendall Clark over at xml.com

Has now written a five-part trilogy diving deep on webarch and it 
doesn't sound like he's finished yet.  He has a some criticisms, some 
of which sound reasonable, but each of which is wrapped up in a couple 
of dozen paragraphs of verbiage.  Virtuous TAG members should try to 
read this, but you're looking at a serious time investment.  I'll drop 
him a note investigating the possibility of a more compact version.
