ELI5: What is a RSS feed and what's the best way to use them?

I know it's some kind of automatic update when blogs + sites release new content, but I don't really know how that all comes together for the user.  Is it worth using them instead of checking several websites daily?

Imagine that you had a friend who loved to tell you stories and you loved listening to because of the way they tell them, but they only tell you stories when you're both in the same place, and if you miss the story, you have to go find them again and get them to repeat it.

So you set up a mutual deal with your friend's sibling, to record the story in writing and put it into a folder for your later viewing. After a while, you go to the sibling and they pull out the folder of stories that your friend has told and let's you read them, taking out your favorites to save for later.

If you have multiple friends who tell stories you can do the same thing with them. Then instead of asking your friends to tell each story individually, you can go to your story-keeper.
