Wikipedia NoFollow Plugin? WikiDigg? another well considered post by Andy Beard, this time a pretty thougt provoking one about the real holy grail of the net, link-juice, and the fact that the blogosphere’s darling Wikipedia appears to give a giant up-yours to the same.
I think an identity based rating system could take wikipedia to the next level, and is essential for the success of the whole ’2.0′ venture provided it’s not just another one-dimensional popularity index with all te depth of soggy cardboard. I imagine transplanting the StumbleUpon as it is now would already be magic, that with a bit of systemic evolution around user-driven configurability and you’d have some pretty serious relevance dynamics kicking in.
… because identity is the commodity that matters.
