On most of the sites I use, manage or built, the primary need is for a WYSIWYG or RTE editor that is simple, lightweight and provides just a small set of simple operations. The most commonly needed operations are: 1. Create a link / URL 2. Insert an image 3. Set something in boldface 4. Set something in italics 5. Create a bullet list 6. Create a numbered list That's it. On these sites, most content is typed in by users, or pasted as plain text. Some users don't know HTML and want some style. Others (like me) are HTML experts, but are not interested in tripling the effort and time to write a short comment by styling it completely with HTML. So I think there are a variety of "use case sets" ranging from the simple situation I just described for my sites, to those who need fancier formatting and the ability to interpret and clean up things like Word doc HTML.
