Google Maps is now highlighting the top contributors by 'reviews, maps and edits' in the map sidebar.
Pointing your mouse cursor at a name of any of the 'top contributors' opens a pop up window with a photograph of the user and some brief information (check out the handsome chap in the screenshot above.
Clicking the person's name takes you to a page with links to all the contributor's My Maps, edit history and reviews. Rewarding contributors in this way could well lead to an explosion in mapping, editing and reviewing on Google Maps.
