It depends on many things. Which industry you work in is one of those things. For a hairdresser, it may be a point. For a company producing steel rods or company that rents out industrial robots, SOME may not be the most effective way to get new customers or communicate with existing ones. The most important thing to consider is whatever the purpose of being in social media for your business. Having a dead profile on Facebook, Twitter or LinkedIN can be worse than not being profiled on social media at all.
