Trendio has closed.
Trendio was the stock exchange for trends. For play money users could buy and sell trends such as personalities, brands or events. The price of a trend was based on how often it appeared in 5000 international media sources, scanned in real time. Trendio rapidly became popular and attracted massive traffic from all over the world, as well as attention from major newspapers, TV-channels and blogs. To develop Trendio as a large-scale web property and an income-generating business would however have required to dedicate time and resources that I wasn't able to provide.
I still believe there is a massive potential for prediction markets, both as games and for their predictive power, especially as the amount of user-generated information publicly available on the web grows exponentially.
