I've noticed an interesting trend in Facebook... more so in the last few months, but I think it's been growing for a number of years. Facebook (and most other social media platforms) has always been intended to bring like-minded people together; to bring friends together. It's been intended to allow people to continue to build relationships when they aren't in the same physical location.
Sometimes it feels as though the purpose of social media has become a place to tell everyone else they are wrong. It seems it's become a place that does a very good job of sowing the seeds of discontent. Because of this trend, I think it completely changes how we market.
