I have asked this question which I don't honestly think is a duplicate of the question linked as motivation for closing. They are both about java, but one is about the language and the other one about its applications in the real world. They are sure related but not exact duplicates by any means. Yet it took just a few minutes to find 5 people willing to close it.
Why is it so? Do similar questions really pollute SO so much? Is closing a question like that so urgent that you can't leave it open for a while and see if it meets interest in the community? Do people just do it because they have the power to do so and they like to use it?
SO should be a community site about programming, not about who's the quickest sheriff.
EDIT: edited subject as I meant "close" instead of "delete"
