These posts (I hesitate to call them questions) are far too broad for Worldbuilding SE.
Not only do they not as specific questions, they more importantly offer no criteria on which to judge the answer.
For example, in almost all of the answers the immediate loss of life due to the virus and resulting accidents is easy enough to predict. So is the resulting panic.
However, from there on each answer focuses on their respective poster's own interpretation and biases. Most see the women survivors as panic stricken, and unable to cope, thus leading to the collapse of civilization. I found it funny that the male survivors would somehow be expected to fare better.
Sexist undertones aside however, how would we know how the survivors may, or may not, pull together to survive, or cling to civilization? How could we possibly understand the implications of such a power vacuum suddenly appearing? Of so many accidents taking place, and so many dead bodies suddenly being left to rot in the streets?
An answer focusing purely on body disposal and the health implications could easily grow to the length of an essay, or even a short novel.
Another answer focusing on putting out the fires resulting from the various planes falling from the skies, or cars crashing into buildings could be similarly complex.
Yet a third focusing on keeping power generation up and going could be a question in an of itself.
While a lot of answers on WB involve some guesswork, this is simply taking it to the next, next level.
Whenever I see incredibly broad but fun to answer questions on WB I cringe a little bit. A part of me wants to join in the fun of imagining the many implications of that catastrophe taking place, and post an answer, or critique existing ones.
However, after 4 months on the site I can clearly tell that allowing this sort of behavior to develop unchecked would turn Worldbuilding SE into the garbage dump of Stack Exchange.
One of the things I thoroughly enjoy about our site is the the quality control which the community performs. How we are quick to help people out with a well thought out answer, however also quick to enforce our standards, rather than open our metaphorical doors to the metaphorical barbarians.
This isn't Reddit, dammit! I expect intelligent questions, and well thought out answers when I log in, and that's the community I want to help keep alive, not one which bows to public opinion and answers silly questions simply because they're "fun".
