Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?
I don't know if this is a known rule yet, but I just tried to post a question beginning with "Hi friends,xyz....".
Automatically, when I posted that question, the post appeared as usual, but the part: "hi friends" disappeared, and only "xyz..." remained.
If that is a known rule (about don't begin the question with "hi everyone" stuff), I think it should be made clearer by notification.
