Feedication is YAFA (see also netvibes, start.com), but again uses all the wrong information - it takes your usernames for a bunch of popular social software sites and displays all your photos/lists/bookmarks etc.
This is the information I want to aggregate: I have a bookmarks folder, opened in separate tabs, that contains my del.icio.us inbox (links from other people), photos from my Flickr contacts, latest world news, what my Last.fm contacts have been listening to, plus a torrent feed aggregator. These things are harder to build presentation modules for, so I just use the original pages from each site, but building a modular portal page using Greasemonkey might still be a possibility.
