I wonder what you think has happened since 2003 that changes the way
well-formatted list postings are constructed? Your frustration seems to
be with those who cannot or will not write a well-mannered message
rather than with the requirements themselves. Top posting may be a
panacea for lazy posting, but best of all is well-thought-out
bottom-posting, which is neither TL;DR (too long-winded to be of 
interest) nor so brief as to be incomprehensible for want of context.

Your final sentence seems to contradict you. Sure, time runs downwards.
So the latest post should be at the bottom?
