Fax number included why?

I can't remember the last time I received a resume by fax (OK, I'll admit that I started recruiting when you only received resumes in person or by fax and that meant that slightly yellow-tinged curly paper..man am I feeling old). The only things I send by fax now are things that need an actual, non-electronic signature (and I still think "can't that company get onboard with eCommerce? It's so 1997!"). I think I have used a fax machine maybe 2 times in the last 6-12 months. So I'm wondering why people still include a fax number on their auto signature or business cards. It just seems kind of weird to me. Is it nostalgia?

I mean, you may as well include your stagecoach stop in your autosig.
