List questions: Community Wiki?
I'm referring to my question here: Java optimizations
I don't completely understand why it was closed. It does not violate any of the reasons stated. I am looking for concrete facts, not opinion. I don't think this question would start a large debate/argument.
The only possible reason I can find was stated in a comment by Goran Jovic:
Anyway, your problem was most likely closed because there is no finite answer to it. It would probably spawn dozens of answers each containing a single optimization. This is usually not considered constructive because it is very easy for initial Q&A format to degrade to a poll.
Perhaps this may be true, but is it necessarily bad? I believe the answers to this question are legitimate and would be extremely helpful/constructive. This is evident in the comments again as two people learned something very useful without even a single direct answer.
I can sort of see why it was closed, but was it really necessary? I was honestly looking forward to the answers and thought others would enjoy learning something too.
