I’m going to link to this discussion from 2009 (exactly 3 years ago) and conclude we really haven’t moved on from there: http://www.mikeindustries.com/blog/archive/2009/04/the-sorry-state-of-wysiwyg-web-editors

I’m a firm believer like you to let editors edit content and not be ad hoc designers but currently we’re still noy there and at this rate of progress it seems like we’re still a ways off.
