Have you heard about this website: zooloo.com? It's new and great if you want to manage several accounts at the same time. You can view your Facebook, Twitter, BBC news, Ebay, Craiglist, Flickr, and emails from Gmail, Yahoo, Hotmail, etc. from a single page! Fantastic! It's free, for a storage limit of 3GB.
This is a sample of how my dashboard looks like. You can also drag and drop your widgets. Try it out and see!
You can also create your own website with zooloo.
