Help needed in testing a new book marketing tool - BookBuzzr

Wanted to ask for some help. But let me first give you a gist of what we do or are doing.:)

We have created a free online book marketing technology for authors - BookBuzzr. (the idea was from an author :) )

BookBuzzr is a page-flipping application that is more suited for marketing books online. BookBuzzr comes with the built-in ability to share book-extracts on over 60 social networking and bookmarking sites such as Facebook, Orkut, MySpace, Digg, Delicious etc.

We are in beta right now and are gearing up for a new release however we'd like authors to try our tool and give us feedback for the new release.

We'd love it if you'd take a look at our tool and share your thoughts with me at freya@bookbuzzr.com

Cheers
Freya
