Depends on your RSS reader! I use “reeder” for Mac and iOS, it does an excellent job of sucking in RSS feeds just from a top-level URL (eg: the verge.com) and keeps everything synced via iCloud. Before that I used feedly in conjunction with a reader app (feedly would keep track of the RSS feeds and keep track of what was read/unread) but honestly I just found syncing with iCloud faster/easier for me personally.

As for finding the feeds, it’s just a matter of curating from the news sites you personally enjoy the most. If you google a site + RSS you can usually find a link to their feed.

Side note: it drives me crazy if a site posts a ton of articles every day, so sometimes I’ll try a site out in my Reeder app, get a feel for it, and sometimes remove it if it becomes too much.
