I think there are also two other problems with WYSIWYG editors that haven't really been solved: 1. They tend to produce output that is not ideal to work with using another program (e.g. your editor of choice). 2. When you make changes to the output, the WYSIWYG editor might not understand it. This very much depends on what is changed, how, etc, but it could be a problem. Both essentially force you to use the same software, and I think that scares people away (rightfully so I'd say).
