Ha, thanks for the advisement and the kind words. We’re very much committed to the open source community and soon we’ll launch Twill.io, our CMS, as open source. The frontend of a website is by no means a trade secret, you can view the source and extrapolate how we did things. From a backend perspective, it uses Twill. If you’d like, you can reach out to Antoine Doury on Twitter (mr_doinel) if you have specific questions about technique (as he was responsible for the frontend).
But yes, if you pose these types of questions via our website contact form, I am certain that our administrative team—tasked with fielding new business and press inquires—will not have the technical answers you seek.
