If you read the post you can see the number comparison (further down the page). Or you can read my summary of the first launch here: http://nathanbarry.com/learned-selling-6000-ebook-today/

I sold about $12,000 in the first 24 hours for my first book.

If anything, the first book is a better indicator of pure marketing-based success, considering that you didn't have a following at that point.

For the record, I'm not asserting that it's bad that you made so much money based on theses factors. I don't expect you not to market you products. If anything, I was commenting on the importance of marketing to initial success.

About how many people were on your email list when you released the first one?
