I came across Start.com today. It's a not-yet-released service MSN is working on, which will house all your feeds (XML, Atom etc, from blogs and the like) in one convenient location. The idea is that you will set Start.com to be your homepage, and thus whenever you open your browser you can see right away what new things there are to read.
It's certainly not the first in this market, but I like the way it's laid out. Go here to get it working for yourself.
