On this somewhat special anniversary, I also want to state once again that Liberapay is an open project. *You* can contribute to it if you have some basic skills, and receive some money in return. There's still a lot of work to do, including quite a bit that doesn't involve programming, and plenty to learn.
Liberapay is written in #Python, #SQL (until I can finish building what's needed to get rid of it), and as little #JavaScript as possible.
