Most of the discussion on the Arc forum is about developing the language itself. Maybe it's that no one discusses other projects, but I don't get the feeling too many people are actually building things in Arc. I haven't done anything large either (I have a decent-sized amount of Arc code, but it's mostly collections of smaller things, e.g., solutions to 50 Project Euler problems), but one of the projects I'm hacking on could become large soon.
