I was very surprised to see that you weren't publishing on iBooks or Kindle, but truly self publishing through your websites. How the heck do you get yourself out there to the point that you're raking in 10k a month? (Besides HN.) And do you think that'll drop off once your main readership has bought the book?
Speaking for myself (Sacha), I raked in 10k a month the first month. That initial boost came mainly from HN. Sales dropped off dramatically since, and now it's probably more around $1-200/month, if that.
