I just came from a not so perfect date but I met her through my marketing ploy, and it goes like this.
I have just completed my book/manual called Rethink Perfect: The Upside of Uncertainty and the art of moderating our own disputes.
As it is a book about and for me and my mating cycle, I created a profile on a popular dating site here in Australia called RSVP using the title of my book as my profile handle, Rethink Perfect.
I used my profile to explain the idea of the book and referred to my blog by the same name Rethink Perfect. Although this is not really allowed, I got away with it. The woman that contacted me said that she loved my profile and even more loved my blog and so I gave her one of my books as a present on my date.
She said that I was using my profile to market my book but I explained I use my book to market myself!
Anyway, obviously this type of marketing would not suit every author but it shows a lateral way of thinking and marketing.
