Description
You can now share your Google Maps edits and reviews with people connected to you on Google+.
That basically means people can now share from Map Maker – which is a crowdsourcing initiative that lets users improve and enrich Google Maps – to their Google+ circles.
All you need to do is navigate to the Map Maker content you’d like to share, such as a specific edit or a neighborhood, hit the ‘Share’ button and select who you want to share it with (choosing from your Google+ circles or individual people, or by email).
