Facebook keeps changing and evolving all the time and this new feature is great for gaining more exposure for businesses (as long as they have a physical location). Basically, if a business facebook page lists an address, people who live near the locality of this address have an option when they visit the page of recommending it. Their recommendation then not only appears on their news feed, but also appears on the business’ wall when their friends visit the page. This is fantastic for building up a fan base.
