We already tried supporting those questions, we even gave them their own site. Sadly, it didn't work out. C'est la vie.
In 2010, a Stack Exchange site called Not Programming Related came out of Area51, the Stack Exchange staging zone. NPR was supposed to be a site where questions that were too subjective / broad for Stack Overflow would find a new home. The site was greeted with enthusiasm, and in theory it looked like a perfect solution: Stack Overflow would remain as laser sharp focused as possible, and NPR would host all those exciting and sometimes helpful (but not really answerable) questions.
However, as it usually happens, theory and practice are two entirely different beasts. NPR's promise proved extremely attractive to people who were more interested in posting joke answers, or just repeating earlier answers, or posting outright crap (Do you fart in the cubicle?). It didn't take long for everyone to realize that the site was not working, and most people just didn't bother with it. Here's what Quantcast tells us for the first year of NPR's existence:
Tons and tons of people visited the site after it went public, but very few decided to stick around. For over a year, the site experienced no growth to speak of. And even fewer people contributed worthwhile content. Turns out that while everyone loves those questions, very few are actually willing to spend any time to answer them (seriously), and maintain and moderate them.
Fortunately, Stack Exchange realized their mistake soon enough. First, Joel warned us that the site was "degrading into fairly stupid water-cooler nonsense" and then Jeff stepped in, and enforced the infamous subjective guidelines. It took more than a few months for people to realize that NPR's (by then already renamed to Programmers) scope had changed drastically. The site had been heavily advertised as Stack Overflow's toilet bowl, and naturally most people believed it was just that, long after the subjective guidelines were enforced.
To make matters even more complicated, there was a small - but solid - group of early members that were attracted to the site by its initial scope and were contributing high quality content. Unfortunately, they weren't enough to maintain a healthy site, and some - if not all - of them were (understandably) quite frustrated after the drastic change. They were doing everything right, and then suddenly the site they were originally promised was no more.
Then came the clean-ups. Changing the scope wasn't enough, we had to change the way we advertised ourselves to the world. Just saying that we were now a serious Q&A site about software design wasn't going to cut it, at least not until we cleaned up all the content that no longer fit the site's scope. After a few months of intense Meta drama, we deleted about 2K questions. And then some. A couple more months passed, but finally we started experiencing growth:
Whatever your opinion of the site's current scope might be, you can't overlook the fact that it only started growing when it became a
vigorously moderated serious Q&A site. Growth aside, every other aspect of the site gradually improved. Hard questions that were once ignored in favour of the latest "let's build yet another list" question are now answered, correctly and relatively fast. More and more people have Programmers as their top site, the one site that they actively and regularly contribute. We are not there yet, but we are certainly on the right track.
The site you seem to want existed for more than a few months, and it failed. Horribly. I'm sorry but I see no reason to try it again.
