This might be how Thanksgiving was started. Colonial analysts predicted the pilgrims would die. Now every year we celebrate that the experts were wrong with turkey, stuffing and that one marshmallow dish that looks like insulation foam.
I remember analysts predicting Facebook was done years ago. Since then its active user base has doubled in size.
Additionally this particular article I read said that teens and tweens are flocking to places like Snapchat. Meanwhile about a week ago there was a report stating that Snapchat has seen a big drop in user activity.
In the grand scheme, it is not a big deal. The medium is not the message. The content I create with my clients can work pretty much anywhere: Social media, websites, newsletters, even a parchment scroll if things go really retro.
