I use google map a lot. Not only for directions! Google map is actually my main travel planner. From arranging walking routes in historical cities to finding best local foods, it helps me a lot during my travel. Couple of yesrs ago, i just realized that the power of google map comes mainly from the network of local guides who share their experiences and then i started to share my reviews especially about restaurants i visit during my stay to give back this community.
My first photo share about local street food restaurant was seen more than 50.000 visitors and I constantly review my activites to share my view for the places i visited.
