Facebook – How to combine the social networking feeds with RSS feeds (such as new questions on WebApps) in a single timeline

With so many different ways to get information on the web (twitter, facebook, myspace, RSS, etc.), I would like to combine them into one place rather than having to run different tools or visit different web sites. Is there a client (web-based or otherwise) that can combine these varying information sources into a single timeline? Preferrably, this would also allow me to update my own status and to respond to items.
