Google Maps has always been an invaluable resource for reviews and information about an area. Now Maps includes "Local Guides", who are featured reviewers that can show you the ropes.
The Local Guide badge is given to top reviewers, so you can help distinguish between the average one-off review from an angry customer and reviews from people who genuinely know their city and want to show off the best spots to others. The criteria to become a Local Guide is at least 50+ reviews. There are also mild perks offered to consistent reviewers you can read about here if you want to work your way up the ranks.
