Allow user to customize page content

Is anyone aware of any news sites where the user is able to customize/personalize the content he or she sees -- sort of like the way you can often select the topics you want to see in an app? For example, I want to see crime news, features and just my favorite sport, but I'm not interested in business, so I select those topics and that's what I see on my version of the homepage or some other "my" page.

I think I have figured out a way to do this, but people here are reluctant to try it because they aren't aware of any sites that do this. If someone knows of a site that does this, I would appreciate the information.
