Email, the Novel

Where have I been for two months? It seems if I'm teaching I don't write. If I'm writing, I'm doing nothing else. Lately most of my writing energy has been in the form of emails. I guess even Faulkner and Proust would have written emails if they'd been around The first novel was an epistolary, Clarissa. I guess that means I could write a novel of emails between two or three people. I could even use a popular medium such as facebook to write a novel. No doubt Coleridge might have written some of his famous poems as Twitter tweets instead of in the popular gothic genre of the day. That said, does that mean I should post my emails and call it the revised epistolary novel?
