RSS FEEDS

I've just finished with RSS Feeds. Do I understand them? In theory I do. Will I use them often? Only when I've figured out exactly what to do. I think I need alot more practice before I can say I have truly figured it out.
Would I use them everyday? Yes, in the areas that interest me. Feeds like news, cooking, travel etc. It's always nice to know the latest.
Would I use it in my work? I'm not too sure at this stage.
