I'm not yet sure why I think this is interesting, but somehow it feels like there are some really nice applications for VoteLinks.
"Trolling is a problem already - Google's PageRank rewards being linked to, so notoreity is valued as highly as popularity. This leads to a 'no publicity is bad publicity' approach. For relentless positivists, the 'vote-against' and 'vote-abstain' values could be taken as signals meaning 'don't index this link'. For Vote tallying, however, positive and negative responses are both valuable and clear. The possibility of a personally filtered search, which reflects your own values expressed by your own links is greatly enhanced by the ability to define negative links as well."
