Before the mass adoption of social networks you would have been hard pressed not to find a site with some variant of the RSS icon. Now it's just the "follow us here" badges asking you to go to someone else's property.
People got out of the habit of following actual sites so RSS buttons largely disappeared.
I've been thinking about this for a while and wondering how and where to reintroduce a button or link to this effect.
Last night, while remodelling the footer menus (not that you'd actually notice) I added a "Subscribe" link which points to the site's RSS feed. In future, I think this may become a page giving different options but it'll do for now.
