There are recurring philosophical questions that generate duplicates, as well as "basic" philosophical questions that are often being asked in the SE. There are Meta questions that discuss this (Fallacy "big list" community wiki question?, Can we please have a "Why do things matter?"/"What is the meaning of life?" question?) in some way, although not directly which is why I'm opening this post.
Yes we have the FAQ post, but it's a general how to behave kind of FAQ, not something really specific to the common philosophical questions that we see every now and then.
Optimally this kind of FAQ would be posted in the "featured" page, or, if possible, in a tab of its own containing those questions instead.
Also topics like "who created the universe", "meaning of life" etc can be discussed in this kind of FAQ, in an explanation post of why this is inappropriate to the SE. This, for example, is a required step in my opinion, as I see a lot of traffic around such topics which ends up emphasizing the prejudice on philosophy nowadays as a nonsense, endless talk on the meaning of life (seriously, this is so upsetting seeing this kind of questions in this SE, I hope I'm not the only one who thinks that way).
