How I Decided to Promote Free Books on Lean Pub

You've been on Lean Pub for quite a few years now. And I was wondering if you could talk a little bit about why you chose us as one of the platforms for delivering your books. It seems to be a real big hub for for technical books, so programming and data science are a really big outlets there. So it's like a home for the tech community, rather than such as a distributor, which takes books on romance or pirates or whatever.
