The service, called EdTwinge, was developed by Mike Coulter, Andrew Burnett, Jim Wolff and digital agency Blonde. They say of the site:
EdTwinge.com is a Twitter-powered review service that collects any tweet that mentions a festival show, then does some clever analysis on whether people like or dislike it,
and provides a realtime Top 10 of acts in each main genre. You can also see what people are saying about each show, and connect with any acts that have a Twitter name.
This "karma" system is particuarly intriguing: if proven to work, it could be extended to hundreds of Twitter topics from restaurant reviews to concert ratings.
