I found the "share a link" pop-up to be annoying (as have others, apparently) and there doesn't seem to be a way to disable it on this site. So I figured out a way to disable it using a user stylesheet mod. This mod, of course, disables it for my browser only and doesn't affect anyone else's experience nor is the site even able to tell I'm blocking it.
But my question is this: can I post my mod here or would be such a post be seen as "teaching people how to hack the site?"
