question about rss readers

I am new to the whole rss world but I have seen the increase usage of rss. I was wondering if with wordpress i would be able to use a rss reader, which i dont know how to use yet, to automatically import articles from few of my favorite sites on to my own website for others and myself to view. If it is possible, i was wondering if some one could guide me or suggest a website. I havent been able to find one about using rss readers to create articles for ones website.

Thank You
