This program mean a lot to me.
It stick people together in many ways. Getting the right info about opening hours of a store or getting well informed by reviews on restaurant.
Looking for best advice for activities in vacation or away from home.
Getting right information at the time you need it by people who already know the real stuff.
It also mean to me to give back then.
So when I visit a place I take time to make a short review to help others. Or, when opening hours of a store changed I give them a refresh :).
