The basic tenet of a CMS system is that it differentiates between content and format, thus making it easier for content creators to focus on content and not look & feel. It also promotes content reuse and hence if same content is shown in different ways, one does not need to re-enter the content.
However, imho, all these rich html controls (eWebEditPro et. al.) discourage the above philosophy. These tools give the power (of misuse?) back to the content guys. Some of these guys are happy because now they are not tied down by the descipline imposed by html forms. However, they end up entering the same content multiple times (main page and printer friendly page for example). I’ve also seen sites where the headline on different articles uses different fonts even though they use a sophisticated content management system.
