True, in addition we lose a lot of time an energy with nonesense things like:
double space or not, write the date on the right or left, the salutation line must match the complimentry close, use open or closed punctuation, indented or in block format, the subject line must come after the salutation line........ I agree sometimes because of style problems content becomes secondary. In fact some polite styles when telling you they are litigating you or increasing your rent make your blood boil. But I still believe hobnobing and telling lies is part of human nature and you won't find so many people around who are always themselves.
all the best
