Personalized knowledge from friends of my new town
Submitted by Hammans
Before moving to Chicago for graduate school in 2009, I crowd-sourced a map of local cultural attractions -- stores, restaurants, coffee shops -- down to what I should order and see nearby. My friends and co-workers who had lived in that area obliged me, making my city experience personalized and an expression of our relationship and theirs to the town.
I was able to port this map to my phone, so wherever I went, I always had a recommendation nearby.
