I had a really good idea while listening to the radio a few hours ago. Websites often have meta tags. The only types of meta tags I know of are description and keywords. But what if there was a location meta tag? Think about it. For many websites, no matter where you live you can still sign up for there services or get information. But many are for a certain area. With location meta tags, I can type in YMCA into google, and if I live in Chicago, it'll put the chicago YMCA first, rather than the San Fransisco YMCA.

Just a random idea....
