Social Mapping

I have started a Sanoodi account. The maps themselves don't appear much different from the usual mapping sites, but Sanoodi does have one advantage. They are making these maps part of a social network. So not only can you get a map of all the activities you've completed in your neighborhood, you can also find everyone else in your neighborhood and contact them. I find the USATF site a little easier when creating a map, but it is impossible to contact anyone else who's mapped any local routes. Well, at least not if you don't want to appear like a creepy stalker. On USATF you can see the runs that have happened in the neighborhood, and the user that mapped them, but you can't see the real life person attached to that username.
