Yes and no. LOL
It depends on the question.
Syllabically challenged or just brief?

The bigger Q is: should all be required to READ the Q prior to answering it?  O.o

No

Just kidding...if someone is gaming the Q & A for points, that's a shame.  But if a question only requires a yes or no response, elaboration may not be adding anything of value.

I know it drives me crazy when he does it, Fred. Maybe we need a minimum of 20 characters to get points. 

Then Roger D. Mucci would get points for his reponse!

Yes. Or no. Sometimes that's all that's needed.

Few questions are "absolute" so it's nice to hear why someone would say yes or no.

Yes

Yes. 

Hi Fred.  I suppose it depends. More than a yes or  no would be nicer but if the question is simple enough and just requires a yes or no, that's ok. Many people like the Q&A section because of its ease of use. 

Yes.

An attorney told me once to JUST ANSWER THE QUESTION THAT IS ASKED OF YOU THEN SHUT YOUR MOUTH.

I do the same sometimes when I type.

I agree with Silvia Dukes PA, REALTOR, CRS, CIPS, SRES ,  Sometimes you don't have to ramble to answer a question.

Sometimes a single word is all that is needed

Yes (it is accepetable). Some questions don't need more elaboration. Short, but sweet and to the point.

1)  Yes.

2) No.

There are times when further elaboration is not necessary.  It shouldn't all be about "points"

I like to keep my head down and eyes on my own paper.

@I agree with Lisa Von Domek 

There are some questions that just need a yes or no and that how I answer but do not answer questions with one words often.

It depends on the question...some are open ended so a detailed response is in order. Others are basically "Yes" or "No" type questions so difficult to expound on those.

Fred,

It is apropriate depending on the circumstance.  Sometimes, I am so surprised by the question, that I find myself being brief and to the point, and at that point, I may feel that my elaboration would fall on deaf ears.  I trust my instincts...If someone wants me to elaborate, they can ask, and I will oblige, so far no one has.  A

I think in some cases a simple "Yes" or "No" is fine.

Depends on the question but it seems acceptable. A good number of questions seem only to need a yes or no. And there is no required number of words.

Some questions can be answered with a Yes or No. Some can not (like yours). 

If we're here to learn and engage, though, why ask (or answer) a yes/no question?

Depends I think - some questions don't require detailed responses

Yes indeed !!

Acceptable? Yes

Must elaborate? No

Sometimes nothing more is needed.

I really think it pertains to the question.

Huh?

What's worse, in my opinion are the multi-part questions and then a link to another post.  

Fred Griffin - Yes.

(And I'd go over the Q&A section in 5 minutes....lol!)

Depends on the question.  An explanation followed by the "yes / no" would be fine also.

No for me, I think some questions need a better answer than one or two words. 

Some quiestions are more like polls... a Yes or No is appropriate.

People need more comments when answering

If the question is appropraite for a yes or no answer then I think it is acceptable to answer that way.

Sometimes yes or no or maybe have the impact that the responder wishes to get across.  Answer the way you see fit.

Depends.

(or should I have said Maybe?)

Depends on the question.  Some can be a simple yes/no answer.

I see often very short answers. I think, if  you do not care about getting 15 points or short on time, it is ok. 

Yes

Yes.

Fred Griffin Yes, because there are some questions that only require a yes or no answer.

YES.....

It depends many people just want them points and shame on them but then again sometimes a simple yes or no is reuqired, maybe the questions should be phrased so that more than a simple yes or no is required.

Both, I like to see other answers, then a short reasoning for why.  Also it depends on the questions.  A simple yes or no is all you need for some.  For those questions, just ask the question and follow it up with "and why?". 

If a yes or a no...there is a lack of intimacy but 100% compliance. Subjective

Yes.

I like Tammy's answer.

YES.

yes

If all that is required is a yes or no then no problemo!

It makes it difficult to comment back when you ask the question and the only answer you get it a yes or no.

Sometimes that's just the answer!

Depends...

I like to write why i said yes or know and if asking a question would want the person answering to say why and not just yes or no

In my humble opinion YES!

Ask a simple question get a simple answer; want to know more make it a better question.

Yes. 

yes

That all depends. So many questions have been repeated so many times. How many times can we answer student questions without a short quick answer?

Yes
