I have to agree that emailing has gotten worse since everyone and all has started using the internet and email. And then tools like Microsoft Outlook make it hard to quote in context and easy to reply above the original message. As a result almost no-one I have regular email contact with has a good email etiquette. If I compare my email conversations with programmers and computer scientists with that of my co-workers or family, the difference is huge. In the former case email is an efficient tool to communicate whereas in the latter case it becomes a pool of mis-communication fast.
