Donald,
Very interesting. Thanks for pointing that out.
There are two aspects to the wiki tribune, the news and the social.
I actually own a large set of domain names (sitting in abeyance) for which I have an idea that would prosper from a loosely coupled network that could replace social media, however its key purpose is to allow connections and sharing with the ability to later retract access . Too big to describe here, but it would benefit from this technology. Perhaps a key addition is a two way encryption in the relationship between every node in the wiki and permitting selective publishing. eg; Share my phone number with family.
The key desire is for everyone to totally own their own data, to update it and even retract after the event.
Regards
Tony
