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.
From What is a "closed", “on hold”, or "duplicate" 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?
UPDATE
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.
