I am asking about the supposed principles that all the users need to follow on Stack Overflow,
There are some cases I want to understand:
Some one asked a question and made it as a wiki -> why all answers are wikis as well "I mean users used to make the answers as wikis, not forced to".
When its better to make a question as a wiki and when not?
When should you make an answer as a wiki and when not?
Whats the real purpose of Wikis on Stack Overflow, while I still see a lot of answers on the same wiki question?
Why wikis questions or answers votes, don't give to their owners more points? "I know its hard to calculate, but its also not fair to gain 100 votes on a question and not get at least one point, we need to think of a way"?
