I just posted this question here to main - a moderator almost immediately voted to close it as off-topic.
I've been around on here long enough to know that my question isn't a lone exception, and that both SU and SE have had their fair share of fun, on-topic questions, but even if that wasn't the case, why? I mean, I get why - because the rules say so - but I just fail to see the purpose of taking such a stringent interpretation of the rules.
It reminds me of MS' archaic, overkill attitude to Easter eggs, but for a company whose userbase is primarily made up of non-technical, corporate users, their stance is at least justifiable. On a site where the vast majority of the userbase are technical users that enjoy the occasional laugh on a workday, I believe there's far more loss to be gained than there is benefit from taking such a hardline stance on this.
The moderator in question, David Postill, responded with:
You should only ask practical, answerable questions based on actual problems that you face... If you can convince me you have a real problem to solve I will happily reopen your question.
This is demonstrably an overly-stringent interpretation of the rulebook that is, at best, applied selectively on SU. Applying it evenly to all of the site's questions would render a good portion of its most highly-voted, on-topic answers as being off-topic. Some are purely informative on a theoretical level, some are a little bit of fun, some are both, like mine. Here are just a few examples from SU that I've managed to find in the last 10 mins, not counting the many, many more I've come across and lost count of on both SU and SO in my time on SE.
Why does Windows think that my wireless keyboard is a toaster?
Why does pinging 192.168.072 (only 2 dots) return a response from 192.168.0.58?
What exactly does the Avast "remind me next century" option actually do?
Difference between .bashrc and .bash_profile
Why are we still using CPUs instead of GPUs?
What are the Windows A: and B: drives used for?
Such questions would only be asked by technical users; as per the common sense definition, they're ostensibly on-topic for the site. They add to users' experience of it, informing them. Just because a question makes users laugh shouldn't make it inherently off-topic. If the rules dictate that, or leave it to the interpretation of moderators to do so, then for consistency, the rules need to be amended, or all such questions considered off-topic and deleted so the site is no longer able to benefit from them.
