Ushahidi is an useful tool. But besides using it to know where the disaster is in Africa, maybe we can develop some other function. During lunch time or dinner time, there are usually lots of peoples at the restaurant. We get to the restaurant, but there is no seat! We are hungry and frustrated. However, we have no choice but to go back home. But, if we use Ushahidi, thing may change. The owner of the restaurant sends out message when his restaurant is already full of people. The circle will become red. We can get the information and we know we can’t go there to have a meal. This way, we won’t waste our time or money. Isn’t that great?
