I'll be the first to ask... do you have a blog post with the lessons learned that enabled your current success? (congratulations, by the way!)
I wrote this post about how I went from the idea to the first paying customer in 7 weeks: http://blog.bufferapp.com/idea-to-paying-customers-in-7-week...
I also write weekly on my personal blog and almost every post has some form of reflection comparing the previous startup with what I'm doing for my current startup: http://joel.is
