Getting input from RSS feeds. The explanation

"Org can add and change entries based on information found in rss feeds and atom feeds. You could use this to make a task out of each new podcast in a podcast feed. Or you could use a phone-based note-creating service on the web to import tasks into org."

— Section RSS Feeds of the online org manual.

doesn't connect my brain to any instance of reality. Anyway, with the description of the manual at hands I was able to produce two sections of rss feeds prepared by

(setq org-feed-alist
      '(("SZ_Ethereum"
         "https://www.sueddeutsche.de/news/rss?search=ethereum&sort=date&all%5B%5D=dep&all%5B%5D=typ&all%5B%5D=sys&all%5B%5D=time"
         "~/org/feeds.org" "Süddeutsche Zeitung, Stichwort Ethereum")
        ("SZ_Blockchain"
         "https://www.sueddeutsche.de/news/rss?search=blockchain&sort=date&all%5B%5D=dep&all%5B%5D=typ&all%5B%5D=sys&all%5B%5D=time"
         "~/org/feeds.org" "Süddeutsche Zeitung, Stichwort Blockchain")))

To update the feeds press C-c C-x g in any buffer with org mode activated. From the second update onwards that key combination generates a :FEEDSTATUS: property list with hashes for feeds. That makes sure that only new feeds are updated.

With C-c C-x G you can open your feed file at the corresponding section, SZ_Ethereum for example.

The process is interesting, but the format of the feeds might be cumbersome. Perhaps an approach with Temple Lang's XML package provides richer versatility.
