Many, if not most, websites publish an RSS feed.e Whereas the Twitter app can only be used to follow people on Twitter, and the Substack app can only be used to follow writers who publish on Substack, you can follow any website with an RSS feed from a feed reader. When you open it, all your reading is neatly waiting for you in one place, like a morning newspaper. And RSS is more of a one-way street from a privacy perspective,f pushing writing out to you with less of your data flowing back to the publisher.
