Back in the day, browsers would have native RSS support. Somewhere around the URL bar of the favourites bar you'd have a little RSS button that would take you to the RSS feed of your choice, as configured by the <link> tags in the HTML. Most browsers have removed RSS, so now you need to either read the HTML (which sucks even if you're familiar with it) or just guess. If you want to instruct the general audience on how to get RSS feeds these days, and you don't want to link to browser extensions (because only a few mobile browsers support them), then "just add /atom.xml" seems like the most foolproof solution to me.
