Personal Information Aggregation: The Next Internet Hotspot?

In fact, FriendFeed just provides a more convenient way for personal network information stream output (the English term is Lifestreaming), and also incorporates some social functions. As far as I know, many of my online friends are using multiple SNS community services at the same time, such as Flickr, YouTube, Twitter, Del.icio.us, etc. As the number of services used increases, the information becomes more and more scattered. How to effectively aggregate them? The emergence of FriendFeed solves this problem very well.
