New look/new word

Here's Kaye Trammell - I note her blog and her newly appeared moblog (left sidebar) show quite different persona. I reckon I'd go so far as to suggest that they are genuine heteronymic works. It's interesting how we adopt different voices in different webspaces. Think voices, think Bakhtin, think heteroglossia. Well maybe that's not at all startling. But do the affordances of different textual spaces change our communicative presence. Mmmm moblog mmmm then are we becoming heteromodal communicators? Hetero, hetero, hetero, any advances on novel uses of the hetero affix as comments please!!
