You may not have heard of Ushahidi before, but it is creating a more prevalent social presence in today’s media-rich world.  Ushahidi takes the concept of mapping to a new wiki-laden level.  Rather than the classic paper map, or even online map, it takes user content and comments and integrates them with a mapping feature.  One food-related use that has emerged is Burger Map.  Whereever one might be in the world, someone can find good burger recommendations from peers.  Individuals can also add to the Burger Map to build upon the utility.

It has gained a following through its social activism uses, but follow your hunger to the Burger Map!
