RSS Rant
Sadly, RSS is like many other platforms without a default client. Well-engineered, extremely useful, but impossible to explain to non-technical people. Before you can use RSS, you have to know what it is, look for it on a website, and have a client downloaded or an account on a web service. For this to make sense you need a mental model of a server with information, a client requesting it, and a technical specification that teaches them to talk to each other.Compare with Facebook or Twitter, where you click a link to the default client and can start using it right away.Ultimately, you can google "Twitter" or "Facebook" and start using the platform right away. Google "RSS" and you get technical explanations, a Wikipedia page, and competing choices for feed readers.
