I started using Google Locals seriously to plan my trip to New York Two years ago. I created lists with router of interesting places to visit and restaurants to go to each day.
Since then every time I plan a trip, Google Locals is my essential tool, in it I consult restaurants where I can go or locations of tourists sites.
Likewise I love writting my opinion and upload my pictures of all the new aires I discover, either in one of my adventures or in the city where I live.
As for me the opinion of the rest of the users is very important, I Like to contribute with my experience, recommending my favourite dishes or giving information about food intolerances.
