This is a meta discussion about the closure of this question.
It was closed as "primarily opinion-based," but I think this is the question to be asked and answered in order to make an informed opinion. The follow-on question, "should I used Meyer lemons as a direct substitute for regular lemons," might be opinion based because each person can weigh the pros and cons differently. However, in order to even make an informed opinion, one needs to know the pros and cons, and that's what the question was asking for.
Existing answers were a good fit for the question and not "oh, it's just personal preference" but instead identified objective facts about differences between the fruits. Why do we not want to allow more answers like that to be posted?
