I found that I don't enjoy Stack Overflow anymore because of many good questions being closed as subjective.
Stack Overflow's slogan says "Welcome to Q&A for professional and enthusiast programmers", looks like professional is no longer a case.
Professionals don't ask simple questions that have single answer, like "How do I make my button red in [insert your framework/API here]." In fact those types of question all have just one correct answer: "RTFM."
Professionals ask complex, subjective questions, that don't have single correct answer, these questions are usually asked to get fellow programmers opinions on subject, to find an alternative point of view on subject.
If the question appears subjective to you this means that you don't have sufficient knowledge on the subject.
