"A viral reaction to an image/video/blog post can occur, but the content cannot be viral through its very nature"
VIRAL CONTENT
Research by Berger and Milkman
Positive content is more viral than negative content
The key to social sharing is the level of emotion of the viewer/reader
Positive content that inspires surprise, amusement and awe is shared more.
Content that inspires sadness is less viral
People share content in the hope that it will raise their social standing, generate reciprocity (i.e. to get something tangible or not in return) and simply to help others
