I think if the question is "How to do X" it becomes very broad and debatable about the implementation.
What I meant is "how to do multisite in Sitecore" is broad and opinion-based question since this can be achieved in various ways and depends on needs of the time. What is the core issue that user faced here or what effort was given is not clear in this.
IMHO One liner question are not good quality post.
Also I would highlight the answer taken from meta-SO answer here
Ok, so let's try to walk through why this is not so good of an idea.
Let's start with a very old opinion-based question, What
non-programming books should programmers read?
Look how many answers there are. 316 of them! That's a lot. That's a
lot even if you wanted to read all the posts. The problem is, none of
these are wrong, but none of these are right. These are all people's
opinions, and you can't tell someone that their opinion is wrong
(except for me, I can say whatever I want). So what can we call "the
answer". Which one should the OP choose?
Now, that is a more extreme example. Let's take something more recent.
How about this recent question. The question boils down to about the
same example question you had: "I have this code base, which has these
vague requirements, and I need to do a task. What is the best way to
approach the problem?"
As of this writing, it has 1 vote for "too broad" and 2 votes for
"primarily opinion based". It's "too broad" because there are too many
possible methods to attack the problem, and it's "primarily opinion
based" because those solutions would be based on the person's opinion.
Yes, maybe in a better question which had the specifications better
defined you would have a narrower set of results, but really, in the
end, most of these questions get opinionated answers. We close these
questions to stop people from giving opinionated answers.
A bad question is ok; a bad answer is BAD. That really kills the site.
Another problem with these types of questions is that it's an excuse
for the author to be lazy. The tool-tip for downvoting includes "does
not show any research effort", and you will be hard-pressed to find a
question like this actually showing any sort of research effort. You
are wanting us to look up either a method or tool for you to use,
instead of making the start yourself.
I always tell people to go to Google first. Say you want to find the
best way to move data between your phone app and your desktop app.
Well, do you know at least one method? Find one, look it up, research
it, figure out if it will work for you or not. Then lookup another,
and maybe a third. We want you to help yourself. Only you can find the
best tool for your job, and spending the extra time researching
yourself will save you, and us, a lot of time.
So your argument to that will be "well we could have one central
location for these types of requests, saving internet readers a lot of
time in research themselves". True, but this brings us back to the
first example in my post: too many "answers", and none of them can be
seen as correct or incorrect.
Bottom line: if we allowed opinionated questions, we would be flooded
with opinionated answers, and voting would be nothing more than a
straw-poll of "which do you like the most". A site reader would have
to parse through so much more content to find what they were looking
for, which is the ANSWER to the question.
