Reading Paul Auster's beautiful-crafted descriptions of facial expression in silent movies (The Book of Illusions) set me thinking about the face as text. It's a Bardic theme (see this title and "your face is a book") and there's loads written about the importance of the face in studies of human communication. But that's face2face in meatspace. Online it's different; not very many faces on our blogs. Maybe that's changing.
