Update 5/23: The Easy Stars are now visible in List view as well as Maps view
There is a new interface feature in Google Maps that allows a user to quickly favor a business listing. A user must be logged in and viewing the listings in the Maps view mode where an outlined star will be visible immediately after the business name.
Upon selecting the star it turns yellow and a the starred listing appears in the user’s MyMaps view (thanks to Stever of AxeMedia for the clue). The yellow star also appears on the listing in the main Map viewing area.
The feature allows a quick and easy way to create a MyMap list of favorite businesses or places in Maps for whatever purpose. Or as Miriam Ellis points out it could also be used to create a list of worsts.
At this point the MyMap is only visible to the logged in user that added the stars but it would be nice if this MyMap’s starred list could used to quickly create sharable public & embedable MyMap.
It is not clear whether the stars impact ranking.
