An excellent article from Aaron Lumnah on self publishing. Become Your Own Publisher: How to Create Your Own eBooks, covers in a nice concise article the ins and outs of self publishing. From why to the numbers, writing, formatting, covers and publishing. One of the things I like is the chart on how to read the Amazon Kindle sales rank numbers. Lots of great info.
Rank Sales Needed to Break in
250k Not many
100-250k Selling 1 every few days
50-100k -1 per day
10-49k Multiple per day
Below 10k Exponential (3k=30-60 per day)
