Sources are extremely important in Judaism, as (almost) every Halacha, or Minhag (custom) has a clear source. Additionally, Judaism places sources and tradition so high, that it is considered fundamental.
The question below, is only discussing the purpose and definition of this site.
There is an assumption taken that in order for an answer to be valid on this site it needs a source.
In this question I will be questioning this assumption, but most importantly trying to get other perspectives (from users of this site).
I feel that there are three different types of questions asked on this site (in the context of this question/discussion).
1) A general question about judaism, or about a specific concept in judaism
Here are some examples of such a question:
Though a source would be really helpful, it doesn't seem necessary.
Furthermore, in some cases I feel it provides less help to the questioner, since sometimes the questioner doesn't have the ability to look up sources, because they are beginner etc.
Obviously not everyone that asks such a question is a beginner, but many times they are (and in the future, it is the type of question that beginners will look at).
2) The questioner brings a source, and has a question about the meaning of it (or a possible contradiction with something else they know)
Here is an example of such a question:
This is a deeper question, additionally the user is showing a deeper knowledge (and skill for learning Torah), yet it doesn't seem 'necessary' to give a source, since the questioner is simply at a loss of where to begin solving his/her dilemma.
As in the first type of question, the user is not always at a loss, at the same time it doesn't seem imperative to cite a source, for it to be a good answer.
3) The questioner is asking specifically for a source, or the only way to resolve the question is through bringing a source
Here are some example of such a question:
Even in this type of question there seems times when an answer doesn't need a source (though it really should).
This is because sometimes the questioner is looking for more info, or another perspective on the matter.
In this type of question, I feel an answer requires a source (almost) all the time, and if it doesn't include one it is not satisfactory.
I feel that most questions on this site do not require a source. The question is: should users enforce the requirement of a source (where the question doesn't need it) or not?
