Rich,
Thanks so much for that perspective. This is a really important point.  
We think that by adding accessible rich text editors that we're  
improving the user experience for everyone, but it seems that the  
accessible rich-text editors maybe a step backwards from text-based  
markup. Text-based markup still has a place and should probably be  
included as an option.
