My recent experience is that I got a paper in PDF, though plain text was more than enough for the paper, and it included an e-mail address to which I send a mail. I used Adobe original PDF reader (version 7.0) and, to make sure that I won't wrongly type or copy the address, used reader's function to automatically detect e-mail addresses in PDF files (PDF may contain hyperlinks and recent PDF reader of Adobe optionally detect additional hyperlinks in text automatically. Both types of links are not distinguishable). Later, I have noticed that the mail failed, because the PDF reader has a bug that the auto detection does not work for e-mail addresses containing "-". IMHO, the person who choosed the PDF format should be responsible for the failure. I hope IETF won't make similar mistakes.
