Add Reviews To Google Maps!
Through this feature, you can write/review and share with the world what you like/dislike and give it a rating of either anything from 1 to 5 stars. To do this, type any area either in Google or Google Maps and select the "more info" link, and then click on the "reviews" tabs. Now, you can write your opinions/reviews which will appear whenever anyone searches for the location, whether he or she searches from Alaska or Vietnam.
This is a good feature, as you will easily receive unbiased and fair, first hand reviews from users all around the world than just one non-deciding, unfair opinion.
