Blog/Podcast Promotion?

I’m embarking on a task that I’m not very good at - self-promotion.  Not for this site, really, but for Sword of Gryffindor.  I need to put a lot of energy into getting as much traffic to that site as possible, for the very simple reason that I’m writing this book that will be published and on shelves by the end of this year, and I want everyone in the entire world to buy it, of course.

Anyone who knows the best ways to increase traffic to a website, I welcome suggestions.  I’ve just started doing this Technorati thing, which is new to me.  Other ideas?
