Looking for a solution to information overload

So as good as Ed's blog and Innovation Daily are, there are many other sources out there.  I've played around with RSS a little bit, but what I'm really looking for is an application that will scan the web for blog posts, papers and other types of information related to some specific topics or tags, and consolidate those for me as a daily or weekly reading list with links.  I'm sure it's out there and I just haven't figured it out yet.  Can any of you help me out?
