Not Your Average User Contributed Map
Today I contributed to a map. I did this yesterday as well. I even did this last week. In fact I've been doing this since the end of July 2009. As of right now I've done this 11,880 times. I'll probably end up contributing to this map again later on today and will almost definitely do it again tomorrow.
But this isn't your average user contributed or crowd sourced map. It's not one of the usual suspects; it's not OpenStreetMap, or Google MapMaker or Nokia MapCreator. It's none of these, but it's a map nonetheless and it looks like this.
