I just approved two edits removing the tag fun-stuff from the two only posts that currently have it:
For one, it seems pointless to have such a small tag. On top of that, it definitely pushes the limits of on-topic (though a bit of fun never hurt anyone, really). On the other hand, it wasn't really hurting anyone as the question count was minimal.* All in all I'm pretty neutral about this, so I approved the edit. I just thought this should come up in meta before we lose the tag. (Tags with no questions get deleted shortly, as per this MSO question.)
So, what's it gonna be? Tag burnination? Tag rescue with tens of volunteers turning up all these fun questions that really needed that tag? Or my personal favourite, a long, slow slide of this question down the meta front page, faced with stone-cold utter indifference? (hey, I could even get a tumbleweed outta that...)
* Yes, I know "minimal" is only one question per tag. Go take this up in math if you feel that strongly about it.
