If anyone wants the tag system to work as intended, surely they'll be annoyed to see all the random tags that are tacked on for comic effect.. sometimes even used to leave anonymous comments that the person don't dare to say under their real names.
Then again, as Tex said, the comical tags can sometime work to disarm tricky situations and bring on lightness to this sometimes-too-serious forum (well ok, not so much lately). This is a good benefit to it too.
