We found a few people do browse wifi networks. However, thats not our target audience. We are targeting people who WANT to get local info. Eg: guests at a restaurant WANT to look at the e-menu. Then the waiter directly them to 100-JohnsRestaurant wifi. Or as we have actually used - people in an event who WANT to get translation were directed to wifi 100-InnovationFair.

Hope it makes sense.
