Inspired by commit message by Prix:
"The japanese culture is interesting to me and as such i would love to learn more and more about it."
And so I thought, why not we expand this proposal to cover the cultural aspect of Japanese society? For starter, it would attract larger audience than with just the language aspect, but more importantly when we are learning the language we cannot escape from having to understand the cultural background behind the language constructs.
For example, to fully answer and understand one of the top on-topic question examples:
How should I refer to members of my family (in-laws) when talking to a third party outside the family, in my families presence?
it would be reasonable and important to include the concept of 'in-group' and 'out-group' in Japanese culture and society.
Another example is the use of honorific forms of various language constructs and their usage as greetings in Japanese. In the Japanese language course that I took in college, the students were taught that おはようございます (ohayou gozaimasu) means "it's early" and not simply "good morning", and having known this it is easily understood that I should not use the greeting at 11AM because it would no longer be "early", unlike the English greeting of "good morning" where you can always use before noon.
So to summarize, I highly recommend that we expand this SE site proposal to include the cultural aspect of Japanese language/society.
