While the expectation is that the 'share' url will be used, in some cases one might want to use the longer main url. Would appending one's user ID make such a link count for the publicity badges (Announcer, Booster, Publicist)?
(I did notice that "/q/question_ID/question-title-text" works and that the question title text appears to be ignored [i.e., different text will still link to the question].)
Since even answer links now count and the title text appears to be ignored, I would guess that such links do count.
