Why is it that everybody that chooses to use industry-standard technology, such as HTML-formatted email, has to suffer these constant complaints from people who refuse to use a standards-compliant mail client?
is compatible with 1960s technology?
I have seen lots of EMail messages, even lots of HTML EMail messages. None (really none!) of them was more useful, more readable, or in any other sense more meaningful than plain text messages just because of the application of HTML. They were all just longer and caused more trouble to some users. (Spam messages are an exception to this observation. :-)
