Does a Web site practically need to do anything to advertise their feed to the diehard RSS/Atom users, other than use the `link` element?
Is there a worthwhile convention for advertising RSS/Atom visually in the page, too?
(On one site, I tried adding an "RSS" icon, linking to the Atom feed XML, alongside all the usual awful social media site icons. But then I removed it, because I was afraid it would confuse visitors who weren't very Web savvy, and maybe get their browser displaying XML or showing them an error message about the MIME content type.)
