WhereMark is another start-up trying to break into the Location Based Services market. Using the site's website, or the iPhone application, users can share and find find local points of interest. Essentially the site enables you to save and share your favourite locations with Google Maps.
To save a WhereMark you need to double click on the map. When you do so an information window opens that allows you to share information about the location. The information window for each saved location includes tabs to view a Street View and get driving directions. From the map sidebar you can choose to view all 'public' WhereMarks or only those submitted by you.
The site includes the option to connect with Facebook and share your WhereMarks with your Facebook friends.
