Google converts them Maps of in a social network. The business has long had a ratings feature it calls Local Guides, where users were encouraged to post photos and share comments about places they visited.
In addition, Google lets you follow “Local Guides” that you consider worthwhile, so you can see their recommendations for other places they've been. If you like what the face X, then it makes sense that you'd want to see what he thinks of other local restaurants, bars, parks, hotels, etc. It's a kind of FourSquare / Yelp. Google has the data, the users, and you are likely to already use Maps from these two applications.
According to a Google statement People in Bangkok, Delhi, London, Mexico City, New York, Osaka, San Francisco, Sao Paulo and Tokyo will soon see the "Top Local Guides" appear on the "For You" tab in the mobile app Maps ”. When you follow one of these Local Guides, their recommendations will appear on Google Maps, just for you, so you can be inspired by ideas for things to do and places to go.
The new feature isn't live yet, at least on device us, but Google says it's coming soon.
