I believe you can also however add on to Atom/RSS. Many feed readers now also support the WebSub [1] standard which allows them to receive instant push notifications of new articles. It kinda speeds up getting things as you don't have to rely on exclusively the pulling model. Sites like WordPress, Blogger, FeedBurner, Mastodon, and Friendica I believe are all examples of sites that support it. It basically extends Atom/RSS to have another feature. Clients that don't support it can still pull like normal. Wikipedia summarizes the technology a bit nicer than the first link [2] [1]: https://www.w3.org/TR/websub/ https://www.w3.org/TR/websub/ [2]: https://en.wikipedia.org/wiki/WebSub https://en.wikipedia.org/wiki/WebSub
