CodingItWrong.com’s RSS feed is at codingitwrong.com/feed.xml
The RSS reader app I use is Feedly; it’s free and works great on (at least) the web, macOS, iPhone, and Android.
To find RSS feeds to add to Feedly, I use the Awesome RSS add-on in Firefox to let me know when a page I’m viewing has an RSS feed, and easily add it to Feedly.
