Oh, and I'm (at last check) 3rd on the second page of Google for eBook Reviews. Woot!
I'm happy to report that I have just made my first sale.

The next step is, obviously, to write more articles. Then set up a Squidoo lens and a Hubpages hub for the gold guide. I then intend to add another review, rinse and repeat.
