Feeds
RSS/Atom and JSON feeds to keep track of new content on this site.
RSS/Atom feed
This is actually an Atom feed, but I call it an "RSS/Atom feed" because the term "Atom" might not be as well-known as "RSS."
JSON feed
This feed is for you if your feed reader of choice supports JSON feeds. The feed follows the JSON Feed Version 1.1 spec.
Following without a feed reader
If you don't use a feed reader, you could try googling "rss to email." There seems to be a few such services, though I have personally never used any service like that so I don't know whether they are good.
If you use IFTTT, you could try out the Subscribe to any RSS Feed applet. It's made by IFTTT itself, so I presume it should work well.
If you use a bookmark manager like Raindrop, you could try googling "raindrop rss" and so on.
Finally, consider also trying out an RSS reader, they are useful! I personally use BazQux Reader and can warmly recommend it (no affiliation).
