There are many questions on this forum that have been commented on and
answered, only later to be voted "on hold" and then subsequently
closed.
Please read this: What does it mean if a question is "closed" or "on hold"? Getting a question closed means that it is off topic or a few other reasons like a duplicate or if the answer is unclear. Closing a question:
1) Does nothing to the answers that people have already written
2) It does prevent further answers from being created
3) And I believe it makes the question not searchable, google picks up questions, why would you want the world to see bad ones?
4) Realize that the moderation system comes from years of experience with SE, the system works and is put in place for SE's goals.
Reasons for holding are irrelevant.
Reasons for holding are relevant, there are reasons why the moderation system was put into place by SE. It works and if it doesn't work you can always talk to a moderator or get it re-opened. Users ask bad questions, it is just plain wrong for people to barge in here and expect an answer to their question with doing little or no work and\or writing a bad question. Bad questions lead to needless discussion. A lot of the closed questions have much discussion about clarification of what the OP meant. Yes there are some people who do not follow the 'be nice' policy, if its a really bad comment then flag it or talk to a moderator.
From the help center:
What types of questions should I avoid asking?
First, make sure that your question is on-topic for this site.
You should only ask practical, answerable questions based on actual
problems that you face. Chatty, open-ended questions diminish the
usefulness of our site and push other questions off the front page.
Your questions should be reasonably scoped. If you can imagine an
entire book that answers your question, you’re asking too much.
If your motivation for asking the question is “I would like to
participate in a discussion about ______”, then you should not be
asking here. However, if your motivation is “I would like others to
explain ______ to me”, then you are probably OK. (Discussions are of
course welcome in our real time web chat.)
To prevent your question from being flagged and possibly removed,
avoid asking subjective questions where …
every answer is equally valid: “What’s your favorite ______?”
your answer is provided along with the question, and you expect more answers: “I use ______ for ______, what do you use?”
there is no actual problem to be solved: “I’m curious if other people feel like I do.”
you are asking an open-ended, hypothetical question: “What if ______ happened?”
your question is just a rant in disguise: “______ sucks, am I right?”
(The above section was adapted from MetaFilter’s FAQ.)
Some subjective questions are allowed, but “subjective” does not mean
“anything goes”. All subjective questions are expected to be
constructive. What does that mean? Constructive subjective questions:
inspire answers that explain “why” and “how”
tend to have long, not short, answers
have a constructive, fair, and impartial tone
invite sharing experiences over opinions
insist that opinion be backed up with facts and references
are more than just mindless social fun
For more detail, read about our guidelines for great subjective
questions and blog post about how real questions have answers.
If your question is about the site itself, please don't ask it here.
