Chrome: While you're used to seeing "Related stories" sections on websites, those lists aren't usually customised to your own interests. This is where Chrome extension Gravity Highlighter can come in handy.
Gravity Highlighter will hide on the left side of your browser while you explore the web. When you're on an article that it might have suggestions for, a tab will pop up and show you a "Your Newsfeed" list of related articles you might be interested in. Over time, it will learn what you like (and you can teach it by giving articles a thumbs-up or thumbs-down).
