Here are two thoughts
Firstly, Is portable reputation overrated?
Do users really care about portable reputation? I know many of the thought leaders, bloggers etc do (for instance with the bill of rights for the social web).
But do users care?
Take me for instance (as a user of social software)
I often speak in Germany or Switzerland.
Every time I speak there, I get requests to connect from a social network called Xing. (The dominant social network in the German speaking world)
A long time ago, I used to be a member of Xing
Now its an abandoned account discovered by German speaking people when I am there
Same with twitter(have an account, don’t use)
So from my own behaviour(and I suspect from others) people simply abandon reputation and start again unless there is a good commercial reasons to ‘port’ the reputation.
Hence, is portable reputation overrated?
Given what I think I know about open social – can we not create an application using Open social APIs that enable reputation to be portable from one network to another (for instance from Myspace to Xing. In fact, we can create an application that aggregates all such reputations in different constituent social networks and creates a ‘consolidated’ reputation (so to speak) across social networks covered by Open Social?
I think this is possible via Open social APIs? (and I continue to explore it – so maybe wrong).
