I just completed another tutorial on how to use Facebook to build relationships within your target audience.  There are easy ways to create communities around a niche for your business.  In this case, I will show you how to build a group of people that are interested in Frisbee.  This is a real good example of how a person who had a site or a bricks and mortar business that sold Frisbees could easily generate a list of people on Facebook that would be interested in your products.
