RSS (real simple syndication) is faster and less time consuming than using a search engine, surfing the web, and then creating a huge list of favourites or bookmarks. It’s been around for a long time and many websites support it. Several of the large platforms, like Facebook, do not, because RSS is an open standard and it is difficult to track users with it. If you listen to podcasts on a ‘podcatcher’ then you are likely using RSS.
