When was the last time you checked Facebook on your computer? For most of us it's become second nature to check all social media platforms directly from our phones, tablets and other mobile devices — and now, maybe even Apple Watch. Sure, we still use our computers when it's convenient. However, the vast majority of us are on the go so much that it doesn't make sense to lug around a laptop when you basically have one right in the palm of your hand. So what does all of this mean for businesses and marketing? Well, basically if you're not already mobile, stop what you're doing and make the switch now.
