Good food are worth sharing, at least to me. Of course, not only food, but interesting places, government department (to bring the awareness so it will be convenient for others) and so on.
Especially good food. To me, if the delicacies are good, sharing it means contributing the the restaurant/business owner, which aids the Growth of GDP spending domestically. At the same time, to let others to have an acknowledgement of such food/place exist, as well as knowing what to expect when they get there.
I have came a pretty long way, since a couple of years ago, into this community.
