I know that I speak for several of the peers here as to why questions posted in the Technical Q&A section may not be answered:
1. The question is unclear.
2. Not enough details are provided.
3. The question is beyond our areas of expertise.
(This is common for Apple, Programming, and "odd" software packages.)
4. Research, or a lot of typing is required and the points are too low to be worth the effort.
5. The peer has a known history of not awarding points.
6. The question is posted in multiple different sections at the same time.
(Pick the "best" category and wait. Please!!)
7. The title does not relate to the question.
I read the title of all the open questions every day I am on-line. If the title makes me believe that:
a. I don't have an answer,
b. other peers would have answered by now,
I don't bother to read the question.
A couple of times, I have been bored enough to go through the old open questions.
1 or more of the above reasons applies to nearly every question that has not been answered.
