Because some might just not know anything about your question and don't want to give you false information , or some just don't feel like talking , writing or anything actually could just end up that no one answers it .
It takes time to get answers,sometimes days or longer.Maybe nobody has the answer, or it was overlooked. You can post the question next week, just make sure not to spam site or it will be taken down. Good luck!

Part of it is the timing of the question---sometimes the people who can answer it are not online. And when we do get on line, there's a limit to how much scrolling we can do to see earlier questions because that scrolling takes a lot of time.
Also various people are good at and / or are interested in only certain types of questions. I enjoy analytic geometry, not so much working with matrices
Also, some questions are designed to have the students develop their own thoughts based solely on written research and not on comments by others. If I sense that (and I may sense incorrectly) I do not answer.
At any rate, if you question has not been removed by the moderators, there is nothing wrong with the question.
