I was reading about Ed Kohler’s post about social networking update redundancy.
I think there can be a simple solution. To do this we may need a simple new standard format of data syndication, which can be a simple derivative of RSS. Basically every individual can have a personal RSS feed.
A person shall provide an input socket (it can be a XML-RPC based system, which already is used by WordPress and several other blogs) when he signs up with any social networking sites or any website where he might update his personal data or make comments or blog posts. These sites can have a system to push the information to this personal RSS feed, which can be the only RSS feed that your friend need to subscribe to know all the latest news about you or your company. I understand that when all data is pushed to the same personal RSS feed, redundancy can be controlled by smart pattern matching algorithm (may be simply matching the heading to start with).
I think this technical solution might work 🙂
Could this work?

One of the Google Tech Talks covered this and I remember seeing that third party sites can collect info from the primary site providing authentication.
Getting updates via RSS can be trouble some.
Folks like Plaxo does similar thing, but in a non-standard mechanism.
