All,
Didn't know if anyone has had a chance to look at the Amazon Kindle. Amazon has done some interesting things with it for those who are authors. You can upload your book and they will convert it to the kindle format. You can then set a price point on the book and sell it to Kindle users.
The Kindle doesn't have a huge base right now, but I see a lot of potential for the current project and future iterations. I'm not sure how the ownership of your work goes with Amazon in the mix, and if a certain amount of what you earn on book sales goes to Amazon.
I just thought of it as a very interesting new idea. You can promote your work via blogs, podcasts, etc then advertise it can be purchased by Kindle users on Amazon.
