Yes, I absolutely agree. You nailed it.
I did a talk about it 1 month ago and described how something hits the social media channels really hard but goes away as fast as it appears. My example was from Syria, too. The little boy in the red t-shirt lying dead on the beach. Remember?
It was probably the most viral picture at that time. Everybody seems to care... everyone was complaining etc.
1 day later it was gone.... out of our heads.... minds.... and social media.
