The concept behind this idea is to enable users to build their own social portal by choosing the different modules available. Besides that, users can also apply different filters to personalize the updates they receive.
Example:
Youtube
Users can personalize to receive Youtube video updates based on title, kind of video, uploader's username, etc.
Last.fm
Users can personalize to receive updates based on music genre or keywords in the song title.
Users can personalize to receive only certain notifications such as Birthday update, comments, replies and so on.
Receive twitter messages.
New modules can be developed to increase the amount of services available to users, such as Email modules, calendar, instant messaging, flickr updates, etc.
