WikiPhilly is about the city of Philadelphia, PA. It has articles about landmarks like the John Wannamaker building and the Wannamaker Eagle in the center of the department store.
It contains listings on the known restaurants and classic take-out joints to snag the ultimate cheese steak hoagies. Psst - it's Jim's on 4th and South. All others are pretenders to the thrown.
This has the potential of a great idea for other cities. What is the embedded knowledge that a local citizen takes for granted and a newbie needs to learn and quickly. This is one idea that I hope other citizens and cities begin to duplicate. http://wikiphilly.com
