I just added a new tag: [`<canonical>`][1] The purpose is (hopefully) self-explanatory: to make it easier to find "canonical" questions/answers when linking duplicates or pointing users to best-practice/consensus answers. I've added a few that I deal with frequently; please add to the list. I'm hoping this tag will also facilitate [tag cleanup/adopt-a-tag][2].
