Interconnected

Carl Steadman's Two Solitudes is a work a fiction by email. Good, and worth enjoying, but it makes me wonder why people haven't attempted to stretch this medium further (I've heard of publicity stunts which did similar things, or involuntary involvement in email "fiction", but nothing that just uses email as the story transport mechanism).
