From the article: Not only will this reduce your anxiety and churn from constantly opening and closing various sites, but RSS also shows the content in a standard format, with less to distract you. Hmm, if you get anxiety from closing and opening tabs, you should probably go offline for a while.
You'll be able to go offline for a while thanks to RSS feeds.
You can click one button to check for feed updates and know you're up to date on things or what's new.
vs.
1) Open browser
2) Load folder of bookmarks for favorite sites
3) Look through each tab to see if there's new content.
To me given those two scenarios RSS feeds seem much more efficient and I do get anxiety when I'm repeating menial tasks potentially multiple times a day for no perceivable benefit.
RSS is another victim of the manipulation of social media companies trying to steal everyone's attention and time.
