RSS feeds are a largely underestimated feature of the web nowadays — at least outside the circles of geeks. Not only they are much more omnipresent than many think (every single respectable news website provides at least one feed); not only they empower users with the possibility of creating their own news feeds and boards through aggregators, without relying on the mercy of a cloud-run algorithm; but their structured nature (under the hood an RSS feed is just a structured XML) offers the possibility to build automation pipelines that deliver the content we want wherever we want, whenever we want, in whichever format we want. IFTTT is a popular option to build custom logic on RSS feeds. It makes it very intuitive to build relatively complex rules such as “send me a weekly digest with The Economist articles published in the latest issue”, or “send a Telegram message with the digest from NYT every day at 6am”, or “send a notification to my mobile whenever XKCD publishes new comics”.
