&gt;I wonder if anyone is building an app that recommends articles that provide a variety of perspectives different from your own.<p>When building Recent News (<a href="https:&#x2F;&#x2F;recent.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;recent.io&#x2F;</a>) we considered adding the options of seeing news from perspectives both similar to and different from your own, at least as we understand them based on your usage.<p>We didn&#x27;t do that. It turns out in early testing that users liked seeing a broad range of articles. For instance, a pro-2A voter might want to read a Salon.com article talking about how firearms should be banned--just to share it to argue how wrong it is! Or an anti-2A voter might be interested in a Fox News article talking about repealing anti-gun laws, if only because it reinforces how nutty those conservatives can be. (It also added more complexity when our goal was an MVP.)<p>The current version of our iOS+Android app includes a personal tab that is unique to you based on what we believe your interests to be, and a Hot News tab that is not unique to you. Neither filters by perspective, and not one person has requested that feature in the weeks since we launched--the feature requests have included things like dark theme, offline mode, text resizing, etc. instead.
