LOS ANGELES -- Shortly after I met Mary Wang, 71, in Chinatown a few years ago, I was drafted to provide tech support for her gift shop business, Jadetime E-gifts.
I set up an Instagram business account for her store, and tried to explain, poorly, how Instagram viral marketing worked.
Rather than being overwhelmed, Mary, who has run the store for two decades, was endlessly curious and eager to learn. She wanted to know how all those new, hip businesses in Chinatown were drawing so many customers.
