You’ve probably heard of RSS or Atom: they are technologies for delivering web content to you. A feed reader is a bit of software (either online or on your computer) that lets you see and organise that content.
I’m not going to try and explain any more about what RSS and Atom are, because it will quickly become confusing (if it isn’t already). What I am going to do is try and explain what a feed reader does, through the following fishy story…
—
Once upon a time there was a vast lake, dense with fish. There were millions of them – of many different species, shapes, colours and sizes – and thousands of new fish appeared every minute.
Each day huge numbers of people would dive into the lake to look at the fish. But many only wanted to see certain kinds: people interested in blue fish only wanted to see blue fish; people interested in red fish with a fin missing only wanted to see those; and so on.
Unfortunately there were just too many fish. People were missing the fish they wanted to see, and the fish themselves were not getting the attention they deserved.
Then one day a group of clever folk invented a special kind of diving goggles. These goggles could be set to display only those fish which met certain criteria. So people who only wanted to see blue fish could now do so with little trouble.
And because the goggles knew which fish the user liked, they could let them know of other fish that they might find interesting.
On top of that, the user could fine-tune the goggles to display exactly the fish they wanted to see (for example they could choose not to see Bob Bigfin, who was an annoying blue fish). They could also set the goggles to automatically tell their friends know which fish they liked.
Of course, lots of people thought this was a great idea and started manufacturing their own goggles. Some gave theirs away free of charge, and some sold theirs with extra features.
And so everyone was able to find what they were looking for in the vast lake, and discover new fish based on what they already liked.

And so it is with your feed reader: you can filter the web for what interests you. The difference is that don’t have to swim around the lake: you see the results all in one place, without having to go back to a website or search engine.
All you need to do is give the feed reader the address for the feed, be it RSS or Atom (you may be given a number of options for different versions of both: don’t worry too much about which to choose, it won’t make much difference). The feed reader then does the rest for you: it looks online and displays anything new almost as soon as it’s published.
