Social media sites like Facebook have become great tools for businesses to reach their customers. With Facebook’s ever-growing presence in the social lives of their consumers, it’s understandable for businesses to want to tap this resource.

In my opinion those hopes and dreams are fuel in the nascent stages of your company, but not usually what happens. It’s Hard It’s hard work finding product-market fit.
