"Successful memes... are those that respond to a particular cultural need or that particularly resonate with contemporary circumstances. In other words, memes that capture the popular zeitgeist are those that are most successful because they are the ones that will capture our attention, inspire a sense of belonging and connectedness with the person who shared it with us, and encourage us to share with others the meme and the collective experience of viewing it and relating to it."
