Doug Cornelius over at KM Space is a prolific blogger.  More importantly, he writes about some really good stuff.  He commented on Now THIS is Social Search about how Vivisimo is doing the Aftervote thing with enterprise search.  Check out Doug’s excellent post on Using Social Search to Drive Innovation through Collaboration for a great explanation.  Here is an excerpt: 

First thing [about Vivisimo's Velocity 6.0 tool] is the ability to vote on whether the item in the search result is useful. It displays the percentage of people that voted up and down. This in turn is fed back into the relevancy algorithm of the search engine. The next step is adding a rating. You can give up to five stars. It also displays the average rating and the number of votes. Administrators can get reports on the rating and use this highlight useful items and bury bad ones. 

Thanks Doug!
