Some Stack Exchange sites, while enforcing regular policies/limits, allow for a little fun now and then, either by letting some “fun” soft big-list questions exist, or by prompting them on specific occasions (I think the site on Judaism has regular fun/soft session near Pessach, but I cannot find a specific reference for that). As this SE blog post explains, it's OK to have some fun, we just don't want the site to be overrun with “fun questions”.
What should our policy be? Do we allow fun questions? Do we need specific occasions for that? Or if we accept them unconditionally, do we have some sort of tacit agreement to keep their number (active fun Q’s at the same time, I mean) reasonable? Do we want them to be community-wiki, as some sites do, so as not to game too much the reputation system? (or do we simply not care?)
Example of “fun” questions I could see, and which I would personally enjoy, would be something like (or subsets thereof):
- what's your favorite research abstract? paper title? TOC graphics? conference title
- what is the most bizarre/extravagant/longest position title you've ever encountered?
- what's the most ridiculously harsh review you've ever received?
