Google Maps is trying to ramp up its "Local Guides" feature by offering new rewards for people who leave reviews and photos, answer basic questions, and update other information. Google describes Local Guides as "a global community that helps you explore the world while earning perks," and the feature is obviously in competition with Foursquare and Yelp in terms of attracting users and reviews of local businesses.
To reward users for the contributions to Local Guides, Google is now offering up to a terabyte of Google Drive storage, early access to new Google products, and the chance to go to a summit for reviewers. Users will earn points for each contribution, and the more points you have, the bigger the bonuses.
