The essence of sharing is a combination of what I like, what I think you’ll like and you’ll want to share with others.
Everyone wants to be the source, the original sharer, of a popular meme. But everyone also wants to participate in spreading it.
On social media, particularly Twitter, ideas, jokes, and information spread like wildfire. We pass the baton until a meme trends; and when it does, we can say we were part of the digital movement.
An idea is just an idea until it becomes social and realized.
