With the RSS Subscription extension for Chrome, you can subscribe to the RSS feed of any website with a click.

If a web page offers RSS feeds, an orange RSS icon will appear in your Chrome’s address bar and, on clicking the icon, you are offered an option to subscribe to that feed in your favorite RSS Reader.

This is a fork of the official RSS Subscription addon developed by Google but it replaces the outdated list of RSS readers (like Google Reader and My Yahoo) with the surviving web-based RSS readers like Feedly and NewsBlur. You can add your own RSS readers as well.
