For those who have historically wondered about or objected to "moderation" (people usually mean
curation here; as the overwhelming majority of the actions they're talking about are
not performed by moderators) on Stack Overflow, here's a hand-picked list of important discussions from the meta site explaining some policy basics:
https://meta.stackoverflow.com/questions/251758 Why is Stack Overflow so negative of late?
https://meta.stackoverflow.com/questions/254262 If your question was not well received, read this before you post your next question

https://meta.stackoverflow.com/questions/260263 How long should we wait for a poster to clarify a question before closing?
https://meta.stackoverflow.com/questions/261592 How much research effort is expected of Stack Overflow users?
https://meta.stackoverflow.com/questions/262446 Are we being "elitist"? Is there something wrong with that?
https://meta.stackoverflow.com/questions/262791 The rudeness on Stack Overflow is too damn high (N.B.: linked specifically for the satire in the top-voted answer)
https://meta.stackoverflow.com/questions/284236 Why is "Can someone help me?" not a useful question?

https://meta.stackoverflow.com/questions/366757 On the false dichotomy between quality and kindness
https://meta.stackoverflow.com/questions/366889 Can we make it more obvious to new users that downvotes on the main site are not insults and in fact can help them help themselves?
https://meta.stackoverflow.com/questions/368072 Comments asking for clarification or an MCVE are not rude/abusive
https://meta.stackoverflow.com/questions/370792 Is this really what we should consider "unwelcoming"?
https://meta.stackoverflow.com/questions/417476 Question Close Reasons - Definitions and Guidance
https://meta.stackoverflow.com/questions/429808 Why should I help close "bad" questions that I think are valid, instead of helping the OP with an answer? (fd: my self-answered Q&A)
Note that IDs are in chronological order. The rate of new meta.stackoverflow.com posts fell off dramatically at some point because of the formation of a network-wide meta.stackexchange.com. The earliest entries listed here are from 2014.
