Thanks for a great read Jim. I've also been doing very well from my own series of ebooks, one of which has remained in the top 10 of it's category since last year (jumping to # 1 several times). Unlike you, I didn't realize the great passive income potential of ebooks until after I put my 1st one out. Since then I've churned out several of them and I haven't looked back.

I won't claim that ebooks have made me rich, but they have provided a very nice supplemental income for me.
