Social network/Information overload

There are so many ways to gather and digest the information flowing through the infosphere.  I enjoy using ScoopIt! and following folks on Twitter, but I must confess- I don't get the point of RSS feeds. I have a Google Reader page, I just don't check it all that often.  Here's why... All the blogs/pages/people I'd want to see on my RSS feed, I already follow either through Twitter, or in Flipboard.  It seems redundant to get the same feeds from multiple sources.  With apps like Flipboard, do we really need Google Reader? Or other feed readers?  Do I need both? Am I missing something? Is it possible to keep up with so many different things, or should I focus on a few key tools?
