Ask HN: Review our location based app - mapTheGraph

Hi,

We are a new location based startup and our first product is a Facebook app.

mapTheGraph ( http://apps.facebook.com/mapthegraph ) is a location based social network, currently integrated with Facebook. It lets you update and share interesting places you've been to on a map. It is a social network that replaces the status update with the location update. Simply double click on the map and we will automatically add details to it and share it.

We would love to hear your views and feedback on this app. Since we are relatively unknown, we are finding publicity a huge challenge.
