Today they're getting even more useful. As you may have noticed, locations and maps are now a part of your Posterous. That's because Posterous has integrated with Google Maps to allow for easy embedding of maps, and automatic geo-tagging to displaying location, complete with mini maps, for photos.
As with everything Posterous creates, benefiting from the Google Maps integration takes little to no effort on your part. Should you want to share your location as a Google Map on your Posterous, all you need to do is paste in the Google Maps URL and Posterous will do the rest. The final result is a fully functional map embed minus the embed code.
Plus, adding geo-data and mini-maps for photos is automatic (you can adjust privacy options in your settings). All you do is post your photos as usual, and Posterous will grab the geo-coordinates and include the location name with an option to display a mini map view. Should you be fond of posting multiple photos at the same time, no worries, Posterous handles the geo-data for all the photos you post, letting you glimpse each locale on the Google Map embed.
