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.<p>Compare with Facebook or Twitter, where you click a link to the default client and can start using it right away.<p>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.
