These short URLs show no clue about the linked question whatsoever. Also, when different people use a short URL for the very same post, then the user id suffix makes those be different URLs for a browser. Such links will then not be shown as visited‡.
I know how to get URLs that have a proper slug. But as I see many of those short URLs pop up on these sites (where referrals are not taken into account for badges), I assume many others just don't realize full URLs would be better for use on these sites themselves? Or many don't want to do the little effort to get the full URL?
So: can we please have an easy way to get the full URL as well, in a way that is easily found for those who don't know about the different links?
(Currently for questions, clicking "link" has the same effect. But then one can also right-click the title, or take the URL from the location bar, to get the full human-readable URL. Once, Jeff thought that was important too.)
† The short links for answers are not (yet) automatically converted into a clickable question title either, unlike links such as
https://meta.stackexchange.com/questions/74274/privacy-leak-in-permalink#75963, which renders as Privacy leak in permalink? But I guess that will change soon.
‡ On Meta the CSS for posts doesn't indicate such difference anyway, which is a different issue.
