What you want is RSS, but you don't need to learn how it works at all. Go to feedly.com and create a (free) account. Add sites you want to follow (there's an 'add content' button which lets you search by URL). Done. Feedly will give you a home page with titles and blurbs, and for many sites you can even get the 'reader mode' content without navigating to the site directly.
