Reading this brilliant book titled Hit Makers: The Science of Popularity in an Age of Distraction by Derek Thompson. It argues nothing really goes viral or becomes an overnight sensation. There's science, repetition, borrowing and bunch of other patterns and events involved. It's not a "how to" book, but it sheds light on how a lot pop culture hits, including art movements as impressionism became so famous. It also taught me that in politics, positive or negative, the tactics in using language are usually similar to be a hit.
Learning a lot from this book. I highly recommend it.
