Have you seen the experimental web-based blog reader from MSN? It is at www.start.com/1/ It has a bunch of links that you can add automatically to connect with some of the top blogs and other RSS feeds on the Internet.
There is an interesting looking bookmark manager at www.start.com/2/ as well. The Bookmark manager only works with IE so far but Firefox support is coming. The Web based RSS reader supports Firefox already.
Still more interesting beta projects from MSN are at http://sandbox.msn.com/
