“Google Reader is still defunct, but its spirit lives on in a “follow button” for Chrome that Google first started experimenting with in May. The RSS tracking feature was limited to the experimental Canary versions of Chrome on Android, but today the company has started enabling it on stable versions of the browser. You can follow a site through the browser’s three-dot menu to subscribe to its RSS feed and have it update in your Chrome app. Sites you’re following will appear in a tab called “following,” which sits along Google’s “for you” tab of recommended articles.”
