I am going to piggyback on the thread about the 'horrors' of having salutations in your question. Nestled deep in the comments of that thread, someone said that using salutations are "not allowed" and there is a "hard rule already" regarding this. I couldn't find such a hard rule written anywhere. (If there is, please point it to me and accept my apologies).
So I must assume that this is some sort of unwritten, community hard rule. And if someone doesn't know about it, they will be dealt with in a manner decided by the powers that be in the community, possibly being embarrassed and/or starting an argument about why something was done a certain way.
I think it would save a lot of time, heartache and general BS'ing around if we just codify these rules and be done with it. It's not like Stack Overflow, et al. don't have written rules already (just check the FAQ ... one of the rules being "Be Nice").
So, what is the proper way to (1) determine whether a rule should exist (e.g., a dictatorship or democratic process) (2) codify that rule once it is determined that it should exist (3) enforce those rules if they are broken?
Let's just get these rules down "on paper".
(I want to make one thing clear as I have been accused by a member of Meta of wanting to do away with community moderation. That is absolutely not true. He claims that community moderation and a set of rules are mutually exclusive. I totally disagree with that assessment.
A huge point of forum moderation is to enforce a set of rules or guidelines for posters...whether they are officially written (some which we have), unwritten (some which we have), assumed (some which we have) or otherwise. All I am asking here is whether it makes sense to put some more rules in the officially written capacity to help in the overall well-being of Stack Overflow. My premise could end up being proved wrong and things remain as status quo, but in no way am I trying to remove the community flavor of this site.)
