That's really cool. It's different from the way we describe people's association with a job or company. You wouldn't say "Steve of Apple", you'd say "Steve, the CEO of Apple". I noticed at SXSWi that people would mention their several blogs; and this was not for self-promotion but because who they are is crucially bound up in their multiple web identities, the different contexts where they're known. Liz of Blogher is definitely different from Liz of Badgerbag; and Liz of both together is a whole new animal.
