When I wrote recently about OpenOffice.org, I remarked in passing that an OO.o-based blogging facility would need a previewer. This provoked a lenghty and thoughtful response from Robert J. Chassell; I asked him to post it so I could point to it, and he has. He’s also posted Four Types of User Interface and notes that there is more to be read at www.rattlesnake.com/notions. Clearly, this man should blog. [Update: He is! Feed here.]
