I can see that there're 3 users who voted to close Most common Software Development mistakes.
I asked in comments to specify any reason, but it's useless.
I read here what reasons can be for closing a question.
1) not subjective 2) not offtopic 3) not duplicate 4) not subjective 5) belongs to SO, because it's programming process related.
So why to vote for close without even specifying a reason? Is it right?
It's not rhetorical or subjective. It tells about mistakes while developing a software. It will help me and others who marked it as favorite to avoid this kind of problems.
