After searching through questions titled "What is/was the significance of ___?" I found many are closed due to being opinion based or off topic, which is not surprising. But there seems to be some variation in what is and isn't acceptable. Just for example, What is the greater significance of the Boer War? was reopened because it became more focused, but this question asking about the significance of a word remains closed despite a title change that made it more specific.
Omitting ones that are closed due to lack of initial research, are questions like this generally considered too vague or open to opinions? I have one regarding a single military encounter and how to measure its impact on the greater war, but I'm concerned it's not specific enough, and therefore not a good fit for the site.
