I saw a thread about this on another site. I was surprised that most people were not taking advantage of this. I think anyone who has a website, should also create a facebook or myspace profile for their company. Another thought is that you could also advertise on facebook and myspace to a specific group of people. You can choose to advertise to people in your area who are between a certain age, married or unmarried, and based on a number of other stuff to. You can really pick and choose who you advertise to on these types of sites and I think it could be a great way to get new customers.
