RSS recommendations

Hi,

I see a lot of Reeder and Instapaper apps on people's homescreens. I used it myself for a bit, with RSS feeds from a few newssites and 9GAG. I don't understand what the point is though, you can easily just go to the website instead of reading it in an app. Maybe you guys can tell me what RSS feeds you follow, so I can understand what the advantage is of having an RSS reader?
