I am preparing a website and noticed that although the source code contains RSS autodiscovery URL, i.e. something like
<link rel="alternate" type="application/rss+xml" href="/rss.xml">
none of the three main browsers actually displays a RSS icon anywhere. I am not sure when this feature went away but few versions back I am quite certain that IE, Firefox and Chrome used to display an orange icon somewhere in the address bar. (Edit: Actually, Chrome never had this functionality, it doesn't recognize RSS at all without an extension.)
Is including an orange icon (or something like that) in the webpage the only certain way how to provide RSS feeds these days?
