The purpose of the example questions is to define what is on-topic, right? I notice that there are badges for high-scoring questions—but none for those ever-so-important edge-case questions. Thus, I propose the following badge:
[bronze/silver] Edge Case: Example question closed as off-topic with 5 or more score
I would also like to propose that this badge be available multiple times—because, well, the more the better!
Additional note: I notice there is no badge-request tag here. Why isn't there?
