Is there any hard data about the percentage of sites that use some kind of a CMS, as opposed to pure hand-coded HTML/CSS?  From my anecdotal experience it really seems that more and more sites use a CMS nowadays, that hand coded sites take too long to set up, require too much time to maintain, are too hard to update regularly, etc. etc.  Pure HTML sites seem insufficient for any but the most basic of websites.
