Questions for people who write programs that they themselves use: 
- for a program that you still use at least once a week, how long ago did you start writing it?
- do you still modify it occasionally?

I guess I'd draw the line at a continuous edit history for the source code, but really, just say if you think something else qualifies from your perspective. Maybe a change of language (and/or of its version) somewhere along the way was just a big edit.
