Get a feed reader, such as Akregator<1>.

Add the various feeds of things you want to follow to it, (e.g. blogs, webcomics, news sites), in many cases this is simply a matter of opening the feed page in a web browser and telling it to use (whatever).

Open the reader and trigger a feed update whenever you want to see what people have posted. Most will periodically trigger updates on their own if you leave them running, (many will 'close' to the system tray so that they can do this).

The whole RSS thing really shines in two cases: Anything with a variable update schedule, (e.g. a 'when I can work on it' web comic), and anything with a heavy stream of posts that you mostly skim over, (e.g. a news site, where most of the time the headline is enough<2>).

<1> The default KDE feed reader, choose one that works with your OS/Desktop Environment. Some are available as browser extensions.

<2> "Justice on the rocks: Zamboni a motor vehicle, judge rules, in DUI case" Do you really need any more?
