Once upon a time, Neil Gaiman was to be interviewed by Elise Matthesen on The Well. And he was, too. But then rather than depart after the interview, he lingered. That conference has since been closed (after 1900 or so posts) and there's now a second one (900 messages and counting).

You can read all the messages there, whether you belong to the Well or not.

Nowadays Neil posts regularly there and to a diary at the American Gods website.
