One more argument against leaning too heavily on social media to promote your business. Cory Doctorow shares the recent news about how Facebook treats businesses and what they may have in mind for the future:
Facebook continues to tighten the screws on the businesses that use the service to market to their customers. Independent research shows that new updates from businesses reach about six percent of the people who follow those businesses. It is rumored that Facebook intends to reduce this number to “between one and two percent” over time. Businesses that want to reach the people who follow them at higher rates will have to pay Facebook to reach them through paid advertisements.
Always remember: your own web site is more important than any other online venue. By using their platform you are helping their business first and foremost, then (if you do it right) benefit yourself.
