A Social Map That Knows The Nearby Restaurants (Or Dry Cleaners) Your Friends Like:
What if Yelp met Google Maps met Twitter? Well. You’d get Citymaps - a cool new app that crowdsources your local businesses.
These days, maps are much more than a guide for getting from point A to point B. They can (sometimes) perfectly time your walking trip so that you don’t miss the next bus. They can tell you where cops are lurking. And they can give you detailed data about nearby locations.

Mapping startup Citymaps thinks it has come up with the next level of utilitarian online maps: a vector-based mobile map with a built-in social network that crowdsources recommendations for businesses.
