I have a multiple-choice quizzing system written in Chicken that's been running at our uni for the past 15 years. It was meant to be a throw-away, to be used for a semester until the bugs in our learning-management system were fixed. But it still gets some use, and has clocked ~350,000 test submissions over the years. Not too shabby for a throw-away. It just runs, and I never think about it... until someone asks a Chicken Scheme question!
