@evan interesting. I have confession to make: when I first saw your polls, the questions were mostly about opinions and points of view, so I thought that "strong" means "I believe so" and "qualified" means "in my opinion", as in "my belief is backed by qualifications".
A while ago I figured that my understanding of intended semantics was wrong, but I still continue voting like that :D
@jonn That's funny! I intend "strong yes" to mean "yes without reservations", and "qualified yes" as "yes, but..."
