I learned from following Stacey Cochran's Kindle success that the key to selling your book on Kindle is conversation.
Stacey has initiated discussion threads that have generated an impressive response. Getting the buzz out about your book translates into sales and reviews.
And don't just stop at Amazon: Just one friend on Facebook plugged *Faking It*'s Kindle debut on her page, and by midnight my sales total doubled.
Call on your Twitter followers. Post discussions on Amazon Kindle discussion groups. Post reviews. Tell everyone you know. There's an iPhone app that lets you download the book as well.
Here's my goal: a minimum of 10 Kindle sales per day for the next 30 days. Help me exceed it!
