Hey Heini, I donīt think they have many partners yet. Overtureīs generous introduction offer is to forget about the minimum monthly fee (25,- Euro) until december. If you have only one SE in a pretty small country (no offense :)) it might be really hard to reach the monthly minimum of 25,- Euro.
Espotting is active in Switzerland for a few month now, and the traffic is close to zero, even for broad topics.
I think in these countrys Qualigo was the early bird, securing bluewin.ch and austronaut.at. If they made long term contracts with both portals, thereīs not that terrible much left in these countries (apart from MSN) for Espotting and Overture. Maybe in the content ads sector?
