>> - No top-quoting, only bottom quoting or in-line I agree with most of these guidelines. I can see most of them makes sense for plain text reading in emails/archives and on phones. The only one I have a problem with is bottom-quoting. With most email clients supporting threading nowadays, it is faster for readers or followers of a thread to do top-quoting. I think if you have specific items that you're answering to then you should trim and do in-line. This email, for example, to me is in-line with one item. If you are replying to an email as a whole, then you should simply top-quote. For the people who are reading archives, it's not too much trouble to follow in reverse but for people who are actively participating in a conversation, it saves a lot of time not to have to scroll down.
