This is a cool project: a wiki-based street map of the world to compete with Google's maps. It's quite amazing how dependent we are on Google to provide mapping mash-ups for the web: geocaching, real estate sales, finding our way to places, business directories etc. Wouldn't it be nice if there was a community-owned alternative that couldn't be turned into a revenue stream at a future date? Well, yes that would be nice. Oh wait.. there is one: OpenStreetMap.org
