Digby is the pseudonym of liberal political blogger Heather Parton from Santa Monica, California who founded the blog Hullabaloo. She has been called one of the "leading and most admired commentators" of the progressive blogosphere.
Digby began as a commenter on the blogs of Bartcop and Atrios and launched her own blog on January 1, 2003, calling it Hullabaloo "because one function of blogs is to cause a ruckus" and decorating it with a picture of a screaming Howard Beale from the film Network. She has been joined by other bloggers on Hullabaloo, including composer Richard Einhorn, who blogs under the name "Tristero".
