You can get more information on anything you want to know about on the web. However, through a traditional search you have to do all of the legwork. When you use RSS sources for feeds, you can have this information compiled and sent directly to you.
To find an RSS source that covers the topics that you want to know about, you do need to do a little legwork on the front end. But once you have the RSS feeds in order, you should not have to worry about searching anymore. You can have information e-mailed to you or sent to your mobile phone.
You can get RSS sources on business topics or entertainment topics. You also can choose the frequency of the feeds that you get. The idea behind an RSS feed is that it makes it as user friendly as possible to get information.
