@Seed,
You need websites with RSS feeds, but those aren't hard to find (any blog or news site will have it, we have a bunch too), and then what it does is put all the different content updates into one interface for you and makes it easier to follow a large amount of content.
Depending on what browser you use, you may see an RSS icon in the address bar when the site has an RSS feed. Then, again depending on your browser setup, you can click on it to add the feed to your RSS reader.
I wrote more about it here:
