This kind of 'humor' blurs the tag cloud though. Its also potentially confusing for a new comer. It also makes tags less functional. If a majority of users prefer it, so be it. Problem is that right now every user can add 2 (nonsense) tags to every thread and these tags are not verified. If you compare that to Slashdot only the most popular tags are shown instead. While here tagging is encouraged its apparently not used in the right way in some threads.
