Is Gillard's income relevant?

Margaret Smyth writes: Re. "Totting up Gillard's income -- author, speaker, ex-PM" (yesterday). What a mean-spirited article about Julia Gillard's income next year, more worthy of The Daily Telegraph than Crikey.  Andrew Crook seems determined to find fault with her, but even he is unable to come up with anything that is not perfectly reasonable in her behaviour.  He is left apparently hoping that Tony Abbot will manage to dud her in some way.
