Good point, Matthew. Getting buzz going can often via Facebook be as easy as asking a question and allowing others on your friends list (or even others in the public) to answer. This can typically spark ongoing discussion, debates, and / or a lengthy conversation – which in turn, can attract even more interest.
Facebook has come a long way over the years in terms of what you can do to generate business, too. For example, you can post videos, as well as comments. You can message people individually or in groups. You can also start a separate page and / or group for your company. By making use of these Facebook attributes, you can literally reach hundreds of thousands (or more) potential customers – all with the simply click of a mouse and a keyboard.
